Visible Optical Windows

An optical glass window is a flat optical component specifically designed for the visible light spectrum (approximately 400–700 nm). Its primary function is to allow efficient light transmission while protecting internal precision optical systems from dust, moisture, or physical damage. These windows are typically made from high-uniformity materials such as BK7 or fused silica, featuring low scatter, low absorption, and low surface roughness. They are widely used in microscopes, camera lenses, spectrometers, and lasers.

Flat optical windows can be classified by material and function:
Materials: BK7, fused silica, sapphire
Functions: protective windows, laser windows, filter windows

Visible laser windows are primarily used in laser cavities for sealing and protection, preventing dust from entering the laser chamber. They can also be used for beam control, serving as output couplers or components in beam expanders.

We currently offer AR coatings, beam splitter coatings, high-reflective coatings, and waterproof coatings. Custom spectral coatings are also available.

Yes, we offer the following customization services:

• Size and shape: Non-standard diameters, thicknesses, or custom shapes (e.g., square, polygonal)

• Material selection: Tailored to match required refractive index, temperature resistance, or mechanical strength

• Coating customization: Optimized for specific wavelengths or angles of incidence

• Special processing: Double-sided AR coating, wedged windows to eliminate interference fringes
