Key Features & Advantages Aplanatic Design: Offers superior imaging and beam control quality for collimated light compared to spherical mirrors. High Surface Accuracy: Utilizing advanced CNC machining and ion beam finishing, surface accuracy can reach λ/10, λ/20, or higher (@632.8nm), ensuring minimal wavefront distortion. Diverse Coating Options: Available with Standard Al, Enhanced Al, Silver, Gold, and high-reflectivity dielectric coatings for specific laser lines, covering UV, VIS, NIR to FIR spectra. High Power Handling: The reflective cooling design and high Laser Damage Threshold (LDT) coatings enable them to withstand extremely high laser power densities without thermal lensing. Multiple Types: Include On-Axis Parabolic Mirrors and Off-Axis Parabolic (OAP) Mirrors, the latter eliminating secondary obstruction for unobstructed beam paths. ...

Working Principle & Core Advantages A full parabolic mirror perfectly focuses collimated light (parallel to its axis) to a focal point. An OAP is a segment of that parabola, whose own optical axis is parallel to the parent's optical axis. Free of Spherical Aberration: Features a parabolic optical surface for perfectly focusing collimated light or collimating point source light, delivering exceptional image quality. Unobstructed Optical Path: This is the most significant advantage. Since the light path does not pass through the center of the mirror, it completely avoids the obstruction, energy loss, and diffraction effects caused by a secondary mirror (or the detector itself) required in traditional on-axis parabolic mirrors. Reduced Stray Light: The unobstructed design significantly minimizes back-scattered light, enhancing the system's Signal-to-Noise Ratio (SNR), which is critical for low-signal detection applications. Simplified Optical Layout: Allows optical engineers to place components like detectors and light sources outside the beam path, facilitating the design of more compact and flexible optical systems.

Coating: Protected Aluminum (Al): Standard coating with good reflectivity from UV to NIR and excellent environmental durability. Enhanced Al/Ag/Au Coatings: Maximize reflectivity for specific bands (e.g., laser lines or IR regions). Dielectric Coating: Designed for specific laser wavelengths, offering reflectivity >99.9% and a very high laser damage threshold (LDT). ...

Coating Protected Aluminum (Al): High reflectivity (~87%~89%) in the visible spectrum, coated with a silicon dioxide (SiO₂) layer to prevent oxidation and scratching. The most common type. Enhanced Aluminum: Features dielectric layers over the aluminum coating to boost reflectivity to over 96% at specific wavelengths (e.g., laser wavelengths). Silver (Ag): Offers the highest reflectivity (~97%~98%) in the visible and near-IR regions, but is prone to tarnishing and often requires a protective cover. Gold (Au): Provides extremely high reflectivity (>98%) in the infrared region (>700nm), but reflects little visible light (appears yellow). Primarily for IR applications. Dielectric Coating: Consists of multiple layers of dielectric thin films, capable of achieving extreme reflectivity (>99.9%) with very low loss. Designed for specific laser wavelengths. Key Features & Advantages High Surface Flatness: The surface is precision-polished to exceptional flatness, minimizing introduced aberrations and preserving the wavefront quality of the reflected beam. High Reflectivity: Utilizing various coating technologies (e.g., metallic, dielectric) ...

Type： Narrow-Band Filter, NBF FExtremely narrow FWHM (usually FWHM < 10nm, down to below 0.1nm in some high-precision scenarios). Applications: Fluorescence spectroscopy, LiDAR, atomic spectrum detection (e.g., screening of mercury lamp characteristic spectral lines). Wide-Band Filter, WBF Features: Wider FWHM (usually FWHM > 50nm), allowing light in a wider wavelength range to pass, balancing the needs of "screening" and "light transmittance". Applications: Color photography lenses (e.g., compensating for light intensity in specific bands), machine vision lighting systems, infrared thermal imaging (screening specific infrared bands). Parameter List: Product name Bandpass filter CWL 245-1064nm FWHM 5nm；10nm; 20nm; 30nm, 50nm or customized Blocking wavelength 200-1200nm or customized Optical density: ...

Cylindrical lens is based on its cylindrical curvature. When light passes through a cylindrical lens, it is refracted or focused along one axis (the cylinder axis) while remaining unchanged in the perpendicular axis. This asymmetric focusing property allows cylindrical lenses to alter the shape of light beams, such as converging or diverging them along one direction while maintaining their original shape in the other direction.   Types of Cylindrial Lenses Single Cylindrial Lenses Double Cylindrial Lenses Triple Cylindrial Lenses Aspheric cylindrial lenses have an irregular shape. Type of Cylindrical Lens Characteristics Common Applications Single Cylindrical Lens One cylindrical surface. Laser line generation, correcting astigmatism. Double Cylindrical Lens Two cylindrical surfaces. Generating laser sheets, circular ...
