Artcraftsブランドは「デザイン性」と「機能性」を兼ね備えた学習教材シリーズです。私たちは、誰しもが、Art(芸術)とCraft & Technology(科学技術)の融合によって、好奇心を高め、もっと楽しくモノゴトの仕組みを理解し、もっと深く感動し、創造的に生きていけると考えます。

The Artcrafts brand is a series of educational material combining design and functionality. We believe that everybody can heighten curiosity, understand while having fun how things work, and be deeply moved and live creatively through combining art, craft and technology.



We have researched light and colors and developed educational material by focusing on sight, one of the five senses of human kind.
By understanding more deeply the “sight” functions which humans have, and by combining them with the newest devices (smartphones, tablets), we create educational tools with which one can have an interest simultaneously in a dream for the universe and in organisms of the earth on which we live.



Children are used to being given a virtual world such as games and finished products, and for them, experiences such as astronomical observation and nature observation are becoming remote existence. Many children can choose among choices but have difficulty creating something by oneself through trial and error.
Renaissance artists such as Leonardo da Vinci were at the same time artists, architects and technicians. We believe that their preoccupation with philosophy, mathematics, optics and natural sciences was the key which prompted the remarkable intellectual and artistic prosperity during the Renaissance.
This trend is connected to the numerous inventions in the 17th century. At present, with the remarkable advances in IT technology, tablets are starting to be used in the educational scene such as schools. It is our hope that our educational tools “DIY smartphone telescope” and “smartphone microscope” will once again stimulate the source of the originally human urge of “I want to know!,” and by arousing children’s curiosity and inquiring mind, lead to a better formative experience.

“Paper” an innovative material Folding technology called “KAMIGUMI”
We created “KAMIGUMI” applying the concept of traditional Japanese “wood joinery*.” We studied ways to fold and join which would make use of the advantages of a familiar paper material (cardboard). The highly safe joinery method “KAMIGUMI” which does not use adhesives or scissors will cause people to renew their appreciation for “paper” which is an innovative material having the duality of strength and flexibility.

* “wood joinery”: a technique whereby incisions, etc. are made in the lumber and joining without depending on nails or metal brackets in making framework for houses. A “traditional construction method” which has been traditionally passed on and refined by Japanese craftsmen.

Feeling the excitement of three dimension arising from two dimension
We planned carefully so that children and adults can develop rich sensibility and creativity through a sense of accomplishment of making something and the experience of being moved by observation.Paper is a two dimensional material, but is very innovative. By bending it, it can be transformed into various shapes. It is also possible to join them by making incisions. With PalPANDA, one can experience that a familiar paper material which anyone can obtain (cardboard), depending on what one makes of it, can become a tool which promotes communication equaling electronic terminals such as tablets and smartphones. While many telescopes are heavy and bulky, PalPANDA made of paper is light in weight and can be immediately carried around and used for observation anytime, anywhere. Applying lacquer or varnish on the surface will protect it from evening dew and it can be used outdoors.

A design which takes into consideration compatibility with camera lenses
The eyepiece lens and the distance between the eyes when looking (eye relief) has been studied.High class imaging ability generated by numerical values found through trial and error. By making the body of the telescope square, the device can be stably fixed, the optical axis is less likely to shift, realizing a high resolution imaging even at high magnification. The eyepiece lens part (eyepiece) can also be used as a smartphone microscope.

Compatible with any tablet or smartphone
It is conceived so that it is not limited to a particulr type of terminal or manufacturer, and can be used with the terminal one owns. *Compatible with “iPhone 7 Plus” too

【 The only smartphone telescope compatible with tablets 】
★The moon (celestrial object can be shown on a large screen, making observation easy
★You only need to adjust the focus once
★You can share the moment and observe together, creating even better communication
★The eyepiece transforms itself into a smartphone microscope (polarizing microscope)
★Take photos and videos and immediately share them on SNS




High precision lenses made in Japan used Objective lenses, eyepiece lenses
In order to reduce lens distortion, achromatic lenses made of two glass lenses bonded together are used for the objective lenses and eyepiece lenses. The entire boundary surface is coated with a 7 layer multi coating and the edge surface is painted black, realizing high contrast and sharp imaging. The diagonal prism is silver coated, securing approximately 96% reflectance, and will not reflect ultraviolet rays of 320nm or less, thus improving the reliability of image sensors of smartphones and tablets.
天体を初めて望遠鏡で観察したガリレオは、望遠鏡の改良と同時に顕微鏡も作ったとされている。スマホ天体望遠鏡 PalPANDAは、望遠鏡の接眼鏡が顕微鏡にもなるというレンズの仕組みについても学ぶことができる。

The future classroom we envision
Galileo who was the first person to observe celestial bodies with a telescope is said to have made a microscope simultaneously while improving the telescope. With PalPANDA, one can learn the mechanism of lenses whereby the eyepiece of a telescope can also become a microscope. Children can enhance the ability to define a problem and attempt to solve it through composite experience such as moving their hands, learning structure and field observations, which may lead to a deeper understanding of organisms, the earth and the universe.


Smartphone 86 microscope Pro & 3D


Freely control the lighting “illumination control boards”
The effects of three dimensionality and contrast of the object under observation can be rendered at will by controlling the illumination with the illumination control board with which one can freely control the lighting. We designed and developed six different kinds of card type “illumination control boards” such as pinhole diaphragm, bright field illumination, dark field illumination and biased illumination.


A design taking into account compatibility with camera lenses
Even though it is of a simple construction of attaching a ball lens (4mm) to a smartphone, it transforms quickly into a microscope of about 86X magnification (about 344X when used together with a digital zoom function) because of its compatibility with tablets and smartphones!


Bright and high precision optical glass made in Japan
High precision optical glass ball lenses used.
Even though it is of a compact composition combining adhesive property rubber lens brackets, it turns into a “water immersion objective lens” by simply applying a few drops of water onto the ball lens part. One can get clear images.

Observation of large objects possible by turning it into an inverted type microscope
The Smartphone 86 microscope made the optical microscope a very familiar item which even a grade school student can handle.It is an inverted type microscope whereby the object (specimen) is placed on top of the lens, compatible with in-cameras of tablets and smartphones, and since there is no need to raise or lower the stage as in existing microscopes, it has superior operational efficiency.Because one can observe the object from the bottom, there is no limit to the height of the object, and large objects can easily be observed in their live forms.Furthermore, because the illumination of an inverted type microscope is in its upper part, one can freely change the illuminating angle, enabling a three dimensional imaging of even a transparent specimen.During the day, natural day light will suffice for illumination. Illumination control boards made of paper with which light can be freely controlled were developed in pursuit of how to gather light and illuminate the object. These are card types, and changing their combination or angles will enable taking photogenic images.

A kit that combines safety and functionality
Safe, not easily breakable round plastic slides with no sharp edges are used.The surface onto which objects are placed is large, and its design is such that it is easy even for children to use.
They come in two thicknesses, 0.8mm and 1mm, and choosing between them depending on the object to be observed enables clearer observations. Because commercially available prepared slides can be observed, the scope of observation is widened, amplifying intellectual curiosity.With this kit and a tablet, field work is possible everywhere, in mountains, at the ocean or riverside, even in the city! You can put a live frog, shrimp or ant in the Petri dish included in the kit and observe it alive! You can observe the details of its skin, its heartbeat, its transparent exoskeleton and the movement of its mouth.


The future classroom we envision
The new observation method which the Smartphone 86 microscope brings about brings closer everyday life and natural science. Children will receive wonders and excitement which cannot be found in computer game software. Who knows, a new view of the world, new values, new technology and art may be engendered from it.
