Filters, a subcategory of our Optical Filters, encompass a variety of specialised filtering components.

We produce filters designed to meet the unique requirements of different optical systems across industries such as medical, life science, industrial and defence sectors.

This subcategory includes Calibration Filters, such as:

  • Didymium and Holmium, which are used for wavelength calibration in spectrophotometers, ensuring accurate and reliable measurements.
  • Dichroic Colour Filters which selectively transmit specific wavelengths of light, while reflecting others, making them ideal for applications such as illumination systems, fluorescence microscopy, and architectural lighting.
  • IPL Colour Glass Filters which are designed for use in Intense Pulsed Light (IPL) systems, that require precise control over transmitted light wavelengths.
  • Photopic Filters which are used to match the spectral response of the human eye, ensuring that measurement instruments like lux meters or photometers provide accurate readings.
