San-In Instrument Co., Ltd. will be exhibiting at the "COMNEXT Next Generation Communication Technology & Solutions Exhibition" held at Tokyo Big Sight. This exhibition is specialized in communication technologies and solutions, consisting of six worlds: 5G/6G communication technologies, 5G/6G materials, local 5G, edge AI/IOT solutions, optical communication technologies, and video transmission. At our booth, we plan to showcase advanced optical measurement instruments for 800G/1.6T, as well as optical components for data centers, satellite communications, quantum communications, and silicon photonics. We invite you to visit the exhibition and stop by our booth.

Lithuanian IBS coating optical system manufacturer Optoman has developed IBS coated mirrors for ArF excimer lasers (193nm). They have achieved a reflectivity of over 98% at an incidence angle of 45°. Optoman is looking for individuals to monitor this product. Size and incidence angle are negotiable. We will provide free samples if you can report on the following points. ◆ 193nm IBS Mirror Monitoring Conditions ◆ Please provide feedback on the following: ○ Durability ○ Reflectivity ○ Any other concerns If you have any questions, please feel free to contact us. Thank you very much.

The "Dubhe" series from OtO Photonics is a spectrometer developed for OCT (Optical Coherence Tomography) applications. It has a spectral range of 800 to 880 nm, a body size of 180 (L) x 120 (W) x 63 (H) mm, and a high resolution of 0.04 nm (with a slit width of 5 µm). There are two models available that support CMOS camera line rates of 80 kHz and 20 kHz. It achieves micrometer resolution and captures depths of a few millimeters. This spectrometer is ideal for integration into OCT devices. Please contact us if you would like to evaluate a demo unit.

This is an introduction to a demo unit from the Taiwanese spectrometer manufacturer, OtO Photonics. We will lend it to you free of charge for up to one week. Please give it a try! ◆Spectrometers◆ 1) UM2280-025-V2 Wavelength range: 330-850nm / Resolution: 6nm 2) UM2380-025-V2 Wavelength range: 330-850nm / Resolution: 6nm 3) UM2390-040-V2 Wavelength range: 330-850nm / Resolution: 10nm 4) RS1680-050-NIRA Wavelength range: 950-1700nm / Resolution: 9-15nm 5) SE2030-010-FUV2A Wavelength range: 180-500nm / Resolution: 0.5nm 6) HB2034-010-NIR1 Wavelength range: 790-1010nm / Resolution: 0.5nm 7) SE1030-010-FUVN Wavelength range: 180-1100nm / Resolution: 1.7nm ◆Light Sources◆ 8) LS-DH-2 D2 lamp + Halogen lamp 200nm～
