Custom Coated Optical Window

Coated optical windows are precision flat optical components with functional coatings designed to improve transmission, reflection, protection, filtering, or wavelength control. They are widely used in laser systems, imaging instruments, optical sensors, spectroscopy, medical devices, infrared systems, and industrial optical assemblies. Realpoo Optics provides custom coated optical windows with different substrates, sizes, coatings, surface quality, and optical performance requirements.

Custom Coated Optical Window for Laser, Imaging and Optical Systems

A coated optical window is used to protect optical systems while maintaining the required optical performance. Compared with uncoated windows, coated optical windows can reduce surface reflection, improve transmission, block unwanted wavelengths, enhance durability, or provide special spectral performance according to the application.

Realpoo Optics manufactures custom coated optical windows in round, square, rectangular, and special shapes. We support a wide range of optical materials and coating designs for UV, visible, near-infrared, and infrared applications.

Typical Coating Options

• Anti-reflective coating
• Broadband anti-reflective coating
• High reflective coating
• Dichroic coating
• Bandpass coating
• Longpass coating
• Shortpass coating
• Metal coating
• Protective coating
• Infrared coating

Typical Applications

Coated optical windows are widely used in laser protection windows, optical sensors, imaging systems, machine vision, spectrometers, medical instruments, infrared thermal imaging, LiDAR, optical communication, aerospace optics, laboratory equipment, semiconductor equipment, and precision optical assemblies.
