Optical Coating
Wavelength Opto-Electronic is Singapore’s leading optics manufacturer, offering advanced optical coating solutions to enhance the performance, durability, and efficiency of your optical components. Our coating capabilities are designed to meet the demanding requirements across industries.
We utilize state-of-the-art technologies and precision process control to deliver high-performance coatings, including anti-reflection (AR) coatings, high-reflective (HR) coatings, and specialty functional coatings across UV, visible, and IR wavelength ranges. Each coating is engineered to optimize transmission, reflection, laser damage threshold, environmental durability, and spectral performance according to your specific application.
Here are several optical coating we do, including but not limited to AR, HD, HR, PR, BC, BS, Filter, DLC etc.

Laser Induced Damage Threshold (LIDT)
LIDT is a key parameter in optics and photonics that measures the maximum amount of laser energy or power a material or optical component can handle before it gets damaged. Essentially, it tells you how much laser intensity a lens, mirror, coating, or optical device can safely tolerate.
