Felix Glass manufactures custom optical prisms from BK7/K9 optical glass, fused silica, borosilicate glass and sapphire. We supply standard and tailor-made prisms for medical equipment, laser systems, industrial machine vision, scientific instruments and surveillance optical systems worldwide. We support drawing-based customization including right angle, penta, dove, wedge, roof, beam splitter and special custom geometry prisms. Services include precision CNC machining, high-quality optical polishing, and UV/VIS/IR multi-layer AR, reflective and beam splitter coatings. This product is classified under Optical Prisms & Optical Components to match engineer search intent for laser, machine vision and medical optical parts. All data shown are typical reference values. Final material, coating, dimension, optical indicators and tolerances shall be confirmed based on official engineering drawings and project specifications. Our precision optical prisms solve common engineering challenges including imaging deviation, light attenuation, optical distortion, low transmittance and unstable optical performance under continuous long-term operation. Tight angle tolerance ensures accurate beam steering, image rotation and beam splitting without obvious optical deviation. Premium raw substrates paired with customized anti-reflection coatings reduce light loss and improve system imaging contrast. Multiple optical glass substrates available to match UV, visible and infrared working spectrum and environmental requirements. Check more optical components in the Felix Glass product catalog. We produce a full range of conventional prisms and accept special-shaped geometry development according to customer optical design drawings. Special shapes and non-standard angles are supported after manufacturability evaluation based on CAD drawings. Felix Glass accepts customer CAD engineering drawings to process all kinds of optical prisms, with controllable dimensions, surface flatness, angle tolerance and edge processing. Strict angle tolerance grinding to guarantee consistent light deflection performance in optical systems. Precision chamfering, flat edge and black shading treatment to avoid stray light interference. AR, reflective, beam splitter coating for UV, visible and infrared wavelength bands. Optical surface defect testing to meet industrial and high-end instrument MIL standards. More manufacturing capability information available on About Us. Different optical substrates have unique transmission range, thermal performance and cost characteristics, selected according to equipment working environment and spectrum. BK7 / K9 Optical Glass: High clarity, cost-effective choice for visible light imaging, machine vision and laboratory instruments. Fused Silica: Low thermal expansion, high laser damage threshold, suitable for high-power laser and UV optical equipment. Borosilicate Glass & Sapphire: High mechanical strength, scratch resistance for harsh industrial environments. Material selection suggestions can be found in the Felix Glass blog. Optical prisms are core components for beam transmission and image adjustment across multiple precision optical industries. Coating scheme and surface quality will be optimized according to your specific application environment. Surface reflection causes light loss, ghost images and reduces imaging resolution. Custom optical coatings effectively improve light utilization efficiency. We supply single-layer and multi-layer coatings covering ultraviolet, visible, near-infrared bands, including anti-reflection coating, reflective mirror coating and beam splitter film systems.

Final manufacturability will be reviewed after receiving customer engineering drawings. After drawing review, material and process scheme are confirmed, the production cycle is as follows: For optical performance, assembly and environmental test verification. Process stability verification before formal mass production. Actual delivery time subject to order quantity, raw material status and coating schedule. Adopt shockproof foam separation and moisture-proof export carton packaging, suitable for sea freight and air freight transportation. The following contents describe conventional performance. Specific indicators need to be confirmed according to project drawings and testing standards. Fused silica is preferred due to low absorption and high laser damage threshold. Send your laser wavelength and power parameters for evaluation. Yes. We evaluate processing feasibility based on your CAD drawings, size and optical tolerance requirements. Yes. Spectral transmittance test data can be provided for batch goods as required by customers for equipment qualification review. Multiple AR coating options for visible and near-infrared bands to improve light transmission efficiency. Angle tolerance depends on prism size. Share your drawing for precise process quotation and tolerance evaluation.
