Product Details

Simultaneously Collimate Light from Laser Diode Fast and Slow Axes
Circularize Elliptical Output from Common Blue Laser Diodes
Ideal for Light Collimation of Single Emitters in the Blue Spectrum

Monolithic Collimators feature a solid glass construction with two orthogonal cylindrical surfaces. The different focal lengths, optimized for numerical apertures of 0.5 and 0.2, simultaneously collimate light from the fast and slow axes of common single emitters. These collimators are capable of producing a symmetrical beam with a nearly round far-field profile. Monolithic Collimators are AR coated to provide high transmission across visible wavelengths and are ideal for beam shaping or laser diode collimation, particularly of blue TO-can diodes with wavelengths of 405nm, 445nm, 447nm, and 450nm.
