we are a high-tech enterprise dedicated to the R&D,production and sales of optical films, optical filtersandprecision optical components.
We operate 100 & 1000 class clean workshopscoveringover 2000 mi, with a total investment of15 million yuan.Our team boasts more than 20 yearsof experience inoptical coating and device design.
Our products are widely applied in digital imaging,projectors,AR/VR, HUD,automotive, medical, laseropticsand aerospace industries. We provide stable,on-time OEM/ODM customization services.
What types of optical filters do you offer?
We offer a wide range of optical filters including Neutral Density (ND) filters, Bandpassfilters, Longpass filters, Shortpass filters, IR/UV cut filters, Dichroic filters, and custom-designed filters. All are available in various substrates (B270, BK7, Fused Silica) andcoatings.
What coating types do you provide, and how to choose the right one?
Two coating types are available: Absorptive ND (no reflection shift, ideal for precisionimaging); Reflective ND (metallic coating, suitable for high-power light attenuation).Select based on your application (e.g., machine vision, spectroscopy).
What is the spectral range and surface quality of your optical filters?
All filters have flat spectral response across 400nm-700nm (visible spectrum) with nocolor shift. Surface quality meets 40-20 scratch-dig standard, and surface flatnessranges from 4 to 10 for low wavefront error.
What types of optical filters do you supply, and what are their mainapplications?
We provide a full range of optical filters, including ND (Neutral Density) filters, IR Cutfilters, Bandpass filters, Longpass/Shortpass filters, and Custom Optical Filters. They arewidely used in machine vision, photography/CCTV, medical imaging, spectroscopy, lasersystems, and scientific research.
What common specifications (size, material, spectral range) are availablefor your filters?
Standard specs include: Size: 3mm-200mm diameter (round), 5mm-300mm(square/irregular, customizable); Material: Optical glass (K9, BK7, D263T), quartz;Spectral range: 400nm-1100nm (visible-NIR), 1100nm-2500nm (mid-IR, customizable);Surface quality: 40-20 to 20-10 scratch-dig standard.
