Optical filters
for machine vision

Schneider-Kreuznach Industrial Optical Filters Group

Filters tailored
to your project

Optical filters improve the performance and accuracy of optical systems by selectively transmitting, reflecting or blocking specific wavelengths or ranges of wavelengths. The filters are critical components in several high-precision applications, including machine vision, spectroscopy, and medical imaging such as fluorescence microscopy. 

Typically made of glass or plastic, optical filters are an integral part of many applications. Be it polarizing filters for life science applications or bandpass filters for biomedical applications, understanding the characteristics of the filters is essential: Dichroic filters, also known as interference filters, reflect unwanted wavelengths and transmit desired wavelengths, while absorptive filters absorb specific wavelengths. 

At Schneider-Kreuznach, we design and manufacture both the mechanics and the coating of our high-quality optical filters. This enables us to produce customized optical filters that meet your exact requirements and guarantee the highest quality standards.



Bandpass Filters

What is a bandpass filter?

A bandpass filter is an optical filter that blocks certain wavelengths or ranges of colors from incident light, allowing only certain ranges of the optical spectrum to pass.

Features of our bandpass filters

  • Average transmittance 95 % 
  • Steep slopes
  • Wavelength tolerance +/-  1 % 
  • Deep blocking / High optical density

Frequently Asked Questions (FAQ)

What are optical filters?

Optical filters are precision devices designed to selectively transmit or block specific wavelengths of light. They improve the performance of optical systems by allowing only desired wavelengths to pass while blocking unwanted light. This selective transmission is essential in a wide variety of scientific, medical, and industrial applications.

What are the advantages of Schneider-Kreuznach filters?

•    Reproducibility and Reliability: Rely on the consistent performance of our filters for precise results, even after years.
•    Optical precision: Highest flatness and minimal wavefront deformation guarantee images without loss of quality.
•    Wide selection: Choose from a variety of filter types and coatings to meet your specific needs.
•    Flexible sizes: Our filters are available in a variety of diameters to suit your applications.
•    Robust Mechanics: Rely on metal mounts for a durable and reliable filtration solution.
•    Highest reproducibility, reliability and excellent image quality.

What are optical filters used for?

Optical filters improve the performance and accuracy of optical systems in many different applications. In fluorescence microscopy optical filters isolate specific fluorescent signals, in spectroscopy optical filters analyze the spectral properties of substances, in medical imaging optical filters improve image contrast and clarity, and in machine vision systems optical filters leverage quality control and inspection processes.

Which filter types does Schneider-Kreuznach offer?

Schneider-Kreuznach offers several types of optical filters that are designed for specific applications:

  • Bandpass Filters
  • Narrow Bandpass Filters
  • Shortpass Filters
  • Longpass Filters
  • Neutral Density Filters
  • Polarizer Filters
  • Color Filters
  • UV-Cut Filters
  • IR-Cut Filters

How do optical filters work?

Optical filters feature materials and coatings with specific transmission and reflection properties. These materials are designed to either transmit certain wavelengths while blocking others or reflect certain wavelengths while transmitting the rest. The design of these filters is based on the principles of interference and absorption, which determine how different wavelengths interact with the filter material.

How do I clean optical filters?

Optical filters require careful handling to avoid damaging their delicate surfaces. Begin by using a soft air blower to remove loose dust and debris. Next, apply a small amount of lens cleaning solution to a lint-free cloth or lens tissue. Gently wipe the filter surface in a circular motion, starting from the center and moving outward. Avoid using excessive force or abrasive materials that may scratch or damage the filter coating.
