Delta White-Light Interferometric Thin-Film Thickness Meter Delta-NIR

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.

VCSEL, short for Vertical Cavity Surface Emitting Laser, is a widely used semiconductor laser component in modern optoelectronics. Unlike traditional edge-emitting lasers, VCSEL emits laser light vertically from its chip surface. Thanks to its low power consumption, stable beam quality, low cost, and easy integration, it has become the core light source for 3D sensing, wearable devices, and high-speed optical communication.

As a professional ultraviolet‑laser solution provider, Precilasers has launched its 266 nm narrow‑linewidth industrial laser, delivering reliable single‑frequency output for high‑precision interference lithography, semiconductor inspection and precision metrology applications.

Precise spectral screening is essential for high-precision medical detection, spectroscopic analysis and intelligent imaging systems. Tailored for visible and near-infrared spectral separation, the SP900 shortpass optical filter delivers high-efficiency light transmission and deep infrared blocking performance. It effectively eliminates stray light interference, improves signal-to-noise ratio (SNR), and serves as a core optical component for biomedical instruments, scientific analysis equipment and machine vision systems.
