Description

BK7 / K9 Optical Glass Lens for Laser & Industrial Optical Systems


Product Overview

Felix Glass manufactures high-precision optical glass lenses made from BK7 (K9) optical glass, widely used in CO₂ laser systems, industrial optical equipment, laser engraving machines and scientific instruments.

These lenses are designed with high transmission, low optical distortion and optional anti-reflective (AR) coatings to ensure stable optical performance in precision laser and imaging applications.

Our optical glass lenses are suitable for both standard optical assemblies and fully customized OEM optical systems.


Key Features
High optical transmittance for visible and near-infrared range
Low distortion for accurate laser beam focusing
AR coating reduces reflection loss and improves efficiency
Available in multiple optical geometries
Stable performance under industrial operating conditions
OEM customization supported
