Sunday Optics has its own coating team and coating designers, specializing in the research and development of ultra-narrow band filter films. Range from UV TO IR Wavelength.

Custom Optical Filters for Precise Light Control

Custom Optical Filters are designed to selectively transmit, block, absorb, or attenuate specific wavelengths or wavelength ranges. By combining high-quality optical glass materials with precision optical coatings, they help control light transmission and spectral performance in a wide variety of optical systems.

Absorption Filters and Interference Filters

Optical Filters are generally divided into two main types: absorption filters and interference filters. Absorption filters rely on the inherent absorption and transmission characteristics of the glass material, while interference filters use multilayer optical coatings to achieve precise spectral control. Depending on the required wavelength, bandwidth, transmission rate, optical density, and working environment, the most suitable filter type can be selected for each application.

Optical Filter Types Available from Sunday Optics

Sunday Optics supplies a comprehensive range of Optical Filters covering ultraviolet (UV), visible, and infrared (IR) wavelengths. Our product range includes bandpass filters, notch filters, edge filters, dichroic filters, color glass filters, neutral density filters, and custom coated filters. These filters can be used to transmit a selected portion of the spectrum, reject unwanted wavelengths, separate light by wavelength, or reduce light intensity evenly across a defined spectral range.

Applications of Optical Filters

Our Optical Filters are widely used in fluorescence microscopy, spectroscopy, clinical chemistry, gas detection, machine vision inspection, imaging systems, sensor calibration, scientific research, instrumentation, medical devices, life science equipment, industrial optical systems, and defense applications. With reliable spectral performance and flexible customization options, they are suitable for both standard optical assemblies and demanding OEM projects.

Standard and Custom Optical Filter Solutions

Sunday Optics offers both standard Optical Filters and custom-made solutions. We can manufacture filters according to your specific requirements, including material, size, thickness, wavelength range, transmission performance, coating type, surface quality, and dimensional tolerance. Whether you need cost-effective filter options or high-performance precision optical filters, Sunday Optics can provide suitable solutions for your optical system.
