Optical Glass Windows

Laser Protection Window, UV Fused Silica Laser Windows, High Damage Threshold Windows Overview: Laser Protection Windows are for applications which require protecting laser output while minimizing stray light and reflections. Star Optic provides high damage threshold AR Coatings on each side of window to make them an ideal solution to be used in front of lasers for material processing for the purpose of protecting the laser optics from hot material drops. General Specificatio

N-BK7 Windows, Uncoated Overview: Star Optic provides high precision windows fabricated from RoHS compliant N-BK7 glass which is typically chosen in the visible and near infrared range due to its excellent transmission in the spectrum. Other materials and various optical coating options are also available for use in a large variety of laser and industrial applications. General Specifications of Uncoated N-BK7 Windows: Material N-BK7 Wavefront Distortion

Brewster Window, Zero Reflection Window, High Damage Threshold Window Overview: Brewster Windows are uncoated substrates that can be used in series as polarizers, or to clean up a partially polarized beam. When positioned at Brewster's Angle, the P-polarized component of the light enters and exits the window without reflection losses, while the S-polarized component is partially reflected. Brewster Windows are primarily used in laser cavities to produce a beam with a high

AR Coated Windows, UV-VIS-NIR N-BK7 & Fused Silica Windows Overview:While uncoated windows have typical losses of about 4% per surface, the Anti-reflective coatings reduce this to Ravg < 0.5%. Star Optic provides various AR Coated Windows use from UV, VIS to NIR wavelength range. For your specific wavelength, please feel free to discuss with us.

CaF2 Windows, Excimer Laser Windows, 180nm-8µM Overview: Calcium Fluoride (CaF2) Window is a popular choice for use with excimer lasers with the feature of its low absorption coefficient and high damage threshold. Star Optic offers either uncoated or with a broadband anti-reflective coating for our Calcium fluoride (CaF2) windows. The uncoated windows provide high transmission from the ultraviolet (180 nm) to the infrared (8 μm). The AR-coated windows feature an antireflectio

Optical Diffusers, Ground Glass Diffusers Overview: Optical Diffuser (Ground Glass Diffuser) with one face polished and the other ground provide a solution for a variety of applications that require a diffuse Gaussian-like distribution. Typical applications include use in screens, illuminator diffusion, and targets. Star Optic offers 120, 220, 600 and 800 grit polishes. Each polish is available in round and square. The various grits provide a range from fine to coarse

UV Fused Silica Windows, Uncoated, High Precision Windows Overview: UV-grade fused silica Wondows are well-suited for applications that benefit from increased transmission deeper into the UV than N-BK7. UV fused silica window also offers a lower index of refraction for a given wavelength, better homogeneity, and a lower coefficient of thermal expansion than N-BK7.

Sapphire Window, Hard Windows, 150nm-4.5μM Windows Overview: Sapphire Windows provide a transmission range extending from the UV to the MIR. The uncoated sapphire windows are designed for applications in the 150 nm - 4.5 μm range. AR coated sapphire windows feature anti-reflective coatings for 1.65 µm - 3.0 µm or 2.0 µm - 5.0 µm on both sides. Sapphire windows are well known for its exceptional surface hardness. They can only be scratched by a few materials other than

Product Description: A drilled hole optical glass window with all faces polished is a specialized type of glass window that has a hole drilled through it and all of its faces carefully polished to achieve high optical clarity and smoothness. This type of window is commonly used in various optical and imaging applications where precise light transmission and minimal distortion are required. Key Features: Here are some key features and considerations of a drilled hole optical
