In strict accordance with the application requirements of red. green, and blue tricolor lasers, Ultraopto has meticulously designed and successfully developed a high-performance achromatic collimating lens. This lens is exclusively engineered to manage the yaser beans with wavelengths of450nm, 488nm, 520um. 635nm, and 670nm, which emanate from a single optical fiber. Considering the innate divergent properties of the light emitted from the optical fiber, the lens system of Ultraopto, through the exquisitely precise structural design of its lens group, has accomplished rernarkable achromatic performance within the extensive spectral range spanning from 450mm to 670nm.
As a result, it effective heuristics the high-quality output of the light beams, demonstrating outstanding technical superiority. Features:It effectively restricts the discrepancy in focal positions within the wavelength bandwidth range to within±2 micrometers. This outstanding performance significantly enhances the confocal properties of multi-wave-length lasers.Excellent collimation effect After collimation, the difference in the beam diameter of the laser beam at the exit is less than ±2.5%, and the difference in the divergence angle is controlled within ±3%, ensuring the spatial consistency of the three-color laser.Excellent optical performance: Wavefront error for a single wavelength: < λ8 (@ 632.8nm, Beam quality factor MP:<1.2Temperature stability: Within the operating temperature range of 10-35C, the focal point drift is less than 2um, making it suitable for various laboratory and industrial environments.
High-quality polarization maintaining design:
Ensuring stable polarization state Crafted with high-quality polarization-maintaining (PM) fibers and polarization-preserving optical design, our Variable Working Distance PM Collimator effectively maintains the polarization state of light throughout transmission. The collimator utilizes PM fibers with high extinction ratio (>25dB) to preserve linear polarization, Precision variable working distance design: enabling flexible adaptation. Our Variable Working Distance PM Collimator is designed with an adjustable mechanism to tune the working distance (WD) according to specific application needs. The collimator offers a wide working distance range (customizable from 10mm to 100mm+), enabling flexible adaptation to different system configurations and target distances. The adjustment mechanism features precision threading and a locking ring for accurate positioning and secure locking of the desired working distance. The non-rotating lens cell design minimizes polarization rotation during adjustment, maintaining the polarization extinction ratio within specifications. The collimator supports both collimation and reverse coupling modes, enhancing versatility for diverse polarization-sensitive applications.
Core performance advantages: Adaptation to polarization-sensitive scenarios
Ultraopto’s Variable Working Distance PM Collimator features outstanding polarization preservation with an extinction ratio >25dB, ensuring reliable performance in polarization-sensitive systems. The collimator offers low insertion loss (≤0.3dB) and high return loss (≥60dB). minimizing signal attenuation in fiber optic systems. It features excellent pointing stability (<1mrad) and mechanical durability, making it suitable for long-term operation in laboratory and industrial environments. The variable working distance design eliminates the need for multiple fixed-distance collimators, reducing system complexity and cost for multi-application setups. The device operates reliably across a wide temperature range (-40℃ to 85℃) and offers resistance to electromagnetic interference, critical for quantum communication and aerospace applications.
