Bandpass Filter

Bandpass Filters – The Perfect Tool for Precise Wavelength Selection

Understanding Bandpass Filters

A bandpass filter is an optical device designed to transmit light in a specific range of wavelengths while blocking all others. This precise control makes it an essential component in applications where accuracy and clarity are essential, such as scientific research, industrial inspection, and medical imaging.

At Optical Filter Shop, we offer a wide variety of optical bandpass filters tailored to cover ultraviolet (UV), visible, near-infrared (NIR), and short-wave infrared (SWIR) wavelengths. Whether you need filters for cutting-edge research or practical industrial use, we have the perfect solution for you.

Our range of bandpass filters

UV bandpass filters

UV bandpass filters are specifically designed to transmit ultraviolet light, making them ideal for applications such as fluorescence microscopy, photolithography and environmental testing. Their precision ensures optimal performance in scientific and industrial configurations.

Visible bandpass filters

Operating in the visible spectrum (400–700 nm), our visible bandpass filters are a reliable choice for tasks such as color detection, machine vision
and light calibration. They provide excellent light isolation, enabling high accuracy in various optical systems.

NIR bandpass filters

For wavelengths in the near infrared range (700–2500 nm), our NIR filters support applications such as spectroscopy, communication systems and remote sensing. Designed for maximum durability and clarity, they deliver reliable results in demanding environments.

SWIR bandpass filters

Infrared filters with Shortwave infrared (SWIR) filters are essential for advanced technologies such as hyperspectral imaging, semiconductor inspection and thermal analysis. Our SWIR filters provide precise wavelength control and superior performance.
