LBTEK high-power laser line reflectors are made with high-purity UV fused silica and ultra-high laser-induced damage threshold (LIDT) dielectric coatings, allowing them to withstand high-energy pulses and offering a higher damage threshold. These reflectors are optimized for efficient reflection in single-wavelength ranges. The UV fused silica substrate of LBTEK high-power laser line reflectors offers better uniformity and a lower thermal expansion coefficient, allowing for better performance during temperature fluctuations and improved resistance to environmental factors. LBTEK high-power laser line reflectors are available for working wavelengths of 266 nm, 355 nm, 532 nm, 780 nm, 1064 nm, 1550 nm, and dual wavelengths of 532 & 1064 nm. The incident angle ranges from 0° to 45°, and the reflectance is over 99%.
LBTEK high-power laser line reflectors are coated with a high laser-induced damage threshold (LIDT) dielectric film, allowing them to withstand high-energy pulses and offering a high damage threshold. These high-power laser line reflectors are designed to accommodate beam incidence angles from 0° to 45°, with a reflectance of over 99%. LBTEK offers two options for the back surface: polished and frosted, providing flexibility for users to apply them in different scenarios.
