Absorption filters are the optical filters that allow the passage of certain wavelengths of light and restrict other wavelengths. Absorption filter manufacturers commonly use dyed glass or pigmented gelatin resins to manufacture the absorption filters. Industrial absorption filters are available in various types such as coloured glass filters, cut-off filters, neutral density filters, polarizing filters, anti-glare filters and UV polarizing filters.

You can use absorption filters in various industries, such as aerospace, metalworking, automotive, pharmaceutical and construction.

Some important parameters you must consider before buying an industrial absorption filter are:

1. The application for which you want to use an absorption filter
   
2. The type of the industrial absorption filter you require
3. The required thickness of the absorption filter
4. The density of the filter
5. The desired colour of the absorption filter
