Near Infrared 700 - 2500 nm Short Pass Filters

A short pass filter in the mid-infrared range between 700 nm to 2500 nm, is designed to allow shorter wavelengths to pass through while blocking longer wavelengths up to a certain cut off point in the near-infrared light range. More on the uses and applications of near infrared short pass filters as well case study examples of filters we have manufactured can be found below.

We design and manufacture custom near short pass filters between 700 nanometres to 2500 nanometres to any custom specification. We hold a wide range of stock substrates such as Glass, Silicon, Sapphire, Infrared Quartz, Calcium Fluoride and more. We are able to offer a complete design and manufacture package in house and dice filters to their finished size with lead times as little as 2 weeks.

Applications

Gas Analysis:

Short-pass filters are used in gas analysis applications to separate specific infrared absorption lines of gases for detection and quantification purposes.

Medical Imaging:

Infrared imaging techniques, such as infrared thermography, use short-pass filters to enhance image quality by filtering out unwanted longer wavelengths and capturing the desired infrared radiation.

Industrial Process Monitoring:

Short-pass filters are employed in industrial process monitoring to selectively transmit infrared signals that carry essential information about the process while blocking background noise or unwanted wavelengths.

Environmental and Remote Sensing:

Short-pass filters are utilised in environmental sensing applications to analyse specific infrared signatures related to pollutants, gases, or other environmental factors.

Security and Surveillance:

Short-pass filters are integrated into security and surveillance systems to improve the detection and identification of objects or individuals based on their infrared characteristics.

Material Analysis:

Short-pass filters are used in infrared spectroscopy and material analysis to isolate specific infrared bands for studying the composition and properties of materials.

Biomedical Imaging:

In biomedical imaging applications, short-pass filters can be used to selectively transmit infrared light for diagnostic purposes, such as in infrared microscopy or spectroscopy.
