Beam-Pointing Stabilization System
In precision optics, thermal drift and stress relaxation can cause low-frequency beam disturbances and sustained spot drift. A highly sensitive camera detects disturbances in real time, while intelligent control dynamically steers an electrically controlled mirror to maintain a preset direction. Unlike other pointing-lock systems, camera detection with small pixels improves locking accuracy. During locking, users can observe spot shape and monitor beam power and its changes in real time.

Optical System for Plastic Film Thickness Measurement UVS3-180-500
Optical Metrology
Jnewtech
Wavelength Range: 180-500nm Grating: 1200line/mm Resolution (FWHM) [MIN FWHM]: 0.2nm (MIN FWHM)
Plastic-film thickness optical system: UV xenon lamp, UV spectrometer and probe. White-light interference uses d = (wave2 - wave1)/deltaWave * K, where wave is wavelength, deltaWave the two-peak separation and K the refractive coefficient. Typical range is 0.5um -100um: approximately 200nm UV for 0.5um films, 500-600nm visible for 10-50um, and 800nm IR for around 80um. Above 100um, vernier calipers are recommended. Transparent films use transmission; opaque films, such as semiconductor etch endpoints, use reflection. A CMOS UV spectrometer and xenon source provide a cost-effective solution, with a JPN detector and USA/Germany hardware. 1. Integrated CMOS/xenon UV system simplifies measurement. 2. A high-performance flashing xenon lamp gives stable UV measurements. 3. Low-cost integration reduces complexity and provides a complete solution.
