LBTEK offers engineered diffusers with selectable divergence angles of 5°, 10°, and 20°. Designed for a wide operating wavelength range of 400 nm – 2000 nm, these diffusers effectively modify the intensity distribution of incident beams, providing non-Gaussian profiles. With transmission efficiency exceeding 90% and a high damage threshold, they are ideal for demanding optical applications.
Each engineered diffuser is pre-mounted in a standard lens tube, with engraved product model, type, and divergence angle on the housing for quick and easy identification. LBTEK also provides custom-engineered diffuser sizes upon request—please contact LBTEK technical support for details.
