Mid Infrared 2500 - 6000 nm Short Pass Filters

Short pass filters in the mid-infrared range between 2500 nm to 6000 nm, are designed to transmit light with shorter wavelengths up to the specified cut off wavelength while blocking longer wavelengths beyond the specific cut off point in the mid infrared. More on the uses and applications of mid infrared short pass filters as well case study examples of filters we have manufactured can be found below.

We design and manufacture custom mid infrared short pass filters between 2500 nanometres to 6000 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 Detection and Spectroscopy:

Short-pass filters are used in gas detection systems and infrared spectroscopy to analyse specific absorption lines of gases in the mid-infrared range for identifying and quantifying gas components.

Thermal Imaging:

In thermal imaging applications, short-pass filters can be used to enhance the contrast and clarity of thermal images by selectively transmitting mid-infrared radiation while blocking unwanted longer wavelengths.

Non-Destructive Testing:

Short-pass filters are employed in non-destructive testing techniques, such as infrared thermography, to inspect and analyse materials based on their thermal properties in the mid-infrared range.

Environmental Monitoring:

Short-pass filters are used in environmental monitoring applications to detect and analyse specific infrared signatures related to environmental pollutants, greenhouse gases, or other substances of interest.

Material Characterisation:

Short-pass filters are used in material characterisation and analysis to study the composition, structure, and properties of materials based on their mid-infrared spectral features.

Security and Surveillance:

In security and surveillance systems, short-pass filters can be integrated to improve the detection and identification of objects, individuals, or anomalies based on their mid-infrared characteristics.

Medical Diagnostics:

Short-pass filters can be used in medical diagnostics for infrared imaging techniques, such as thermography, to assist in the detection and diagnosis of diseases or abnormalities based on thermal patterns.

Remote Sensing:

Short-pass filters are applied in remote sensing applications to enhance the detection and analysis of specific targets or features by isolating relevant mid-infrared wavelengths.
