• Optical Experimental Parts

- Compact size with an outer diameter of φ8mm - Achieves uniform illuminance distribution

• Laser marker

- It can efficiently convert weak light in the range of 200 to 400 nm into visible light. - It has high resolution due to the dispersion of a large number of luminescent ions. - It is transparent, highly homogeneous, and has excellent machinability, allowing it to be processed into various shapes like other optical glasses. - It has excellent water resistance. - There is almost no degradation in performance even after prolonged exposure to ultraviolet light.

• Analytical Equipment and Devices

The high-precision glass mold "Fly Eye Lens" is ideal for the uniformity of laser and high-power LED light sources. Being made of glass, it has excellent heat resistance and can be used over a wide wavelength range. We will respond to your optical design needs based on customer requests. 【Features】 - Fly Eye Lens made from precision glass mold forming - Ideal for the uniformity of laser and high-power LED light sources - Excellent heat resistance due to being made of glass - Usable over a wide wavelength range - Optical design support based on customer requests For more details, please contact us or download the catalog.

• Glass

Inside the phosphorescent glass, the movement of electrons occurs due to light energy, and these electrons are temporarily stored in areas called traps, which gradually return to their original state, resulting in prolonged luminescence.

We have achieved a micro lens array that complies with the "Telcordia standards" using precision mold molding with glass materials that excel in environmental resistance and temperature characteristics. You can choose between options for collimators and LD coupling. Additionally, we have realized low-cost, mass production (capable of over 10,000 units per month) by leveraging mold production.

This is an aspherical lens from a glass material supplier who knows the materials inside and out. We have over 30 years of supply experience. Taking advantage of the flexibility typical of small and medium-sized enterprises, we can accommodate small lots starting from just one piece. While aspherical lenses have become quite common and are often seen, when you actually place an order, you may find that suppliers are unwilling to accept small quantities or that the prices are too high. Do you want to reduce costs on aspherical lenses after prototyping with catalog products, or do you have custom requests? Please feel free to contact us at [Sumida Optical Glass].

• filter

This is a compact ultraviolet sensor that can continuously monitor whether a certain amount of light is present. It can stably monitor even high-power ultraviolet light. 【Features】 ■ Small and space-saving. ■ Equipped with an answer-back output. ■ Available in two modes: light quantity mode and integration mode. ■ The sensor head has wavelength selectivity for 365nm and 254nm. ■ By using a waterproof sensor head, stable measurements can be taken even underwater. ■ Both analog voltage and analog current outputs are standard and switchable. *For more details, please request materials or view the PDF data from the download section.
