Linear Variable Neutral Density Filter

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.

Driven by the rapid upgrading of intelligent vehicles, optoelectronic sensing technologies represented by laser sensing and infrared thermal imaging have become core pillars for high-level autonomous driving and smart cockpit iteration. Leveraging automotive-grade optoelectronic R&D advantages, Pilot Technology Group launches the VITAL intelligent vehicle solution. By integrating high-power VCSEL laser chips and vehicle infrared night-vision thermal imagers, the system comprehensively enhances vehicle environmental perception and realizes safer, smarter and more comfortable driving experiences.

In UV laser testing, UV spectroscopy and lithography optical experiments, excessive light intensity will lead to detector saturation, optical component damage and overexposed imaging.

Founded in 2003, BWT Beijing Optoelectronics adheres to the mission "Let Dreams Fly With Light" and vision of becoming a Global Leader in Laser Solutions, guided by the core value "Innovate to Achieve Extraordinary".
