420nm Longpass Filter

Founded in 2019, Jilin JC Ultrafast Equipment Co., Ltd. is a high-tech enterprise incubated by the Ultrafast Optoelectronics Center of Jilin University. Our R&D team owns 15 years of profound experience in femtosecond laser micro-nano fabrication.

Polycom Photonics Co., Ltd focuses on the R&D and mass production of high-stability, narrow-linewidth laser sources for optical sensing applications. The company provides cost-effective and high-precision optical sensing lasers with a wavelength coverage from 689nm to 2350nm. Featuring accurate wavelength control and outstanding spectral stability, these laser products are widely applied in atomic spectrum detection, element precision measurement and professional optoelectronic sensing systems.

As premium broadband light sources situated between traditional LEDs and laser diodes, MicroLight superluminescent‑diode (SLD) products combine broad spectral bandwidth, sufficient optical output power and low‑coherence performance.

Driven by the continuous pursuit of higher precision and efficiency in optical communication and optoelectronic device manufacturing, OLCR-1000 Low-Coherence Interferometer, independently developed by Wuhan Guanggu Interconnect Technology Co., Ltd., provides an innovative technical solution for distributed return loss testing of optical fibers and optoelectronic devices.
