Customized Laser Cutting Lens Spherical Optical Lens Laser Protective Windows BK7 Glass Lens

We specialize in custom manufacturing various shaped glass laser protective window plates. Beyond standard windows, we offer comprehensive customization services according to customer specifications.

Our windows are manufactured from premium materials including N-BK7, fused silica, sapphire, CaF2, silicon, and other optical glasses supplied by our company. We accommodate requests for windows of any size and shape—round, quadrate, triangular, or other polygonal forms—with optional single or multiple layer AR, HR, or PR coatings.

As a professional customized-oriented optical company, our product portfolio includes prisms (triangular, penta, roof) and lenses (plano convex, plano concave, biconvex, biconcave) in various sizes and shapes.

The Customized Laser Cutting Spherical Optical Glass Lens Protective Windows BK7 is a high-precision optical component engineered to protect sensitive laser systems while maintaining excellent optical transmission and beam integrity. Manufactured from premium BK7 optical glass, this protective window combines outstanding optical clarity with reliable mechanical strength, making it suitable for demanding laser cutting and industrial processing environments.

BK7 glass is widely recognized for its stable refractive index (~1.517 at 587.6 nm), low bubble and inclusion content, and high homogeneity, ensuring minimal distortion when transmitting laser beams. The spherical surface design can be tailored to meet specific system requirements, including slight beam correction or controlled optical performance where needed. Unlike standard flat windows, spherical optical windows provide additional flexibility in optical path design, especially in compact laser assemblies.

This product acts as a barrier against contaminants such as dust, spatter, smoke, and debris generated during laser cutting processes. Optional anti-reflective coatings can significantly reduce Fresnel reflection losses (typically ~4% per surface for uncoated BK7), improving transmission efficiency and ensuring stable laser output. With customizable diameter, thickness, curvature radius, and coating options, this protective window offers a reliable and adaptable solution for modern laser systems and precision optical equipment.
