When it comes to optical filters, there are various types available in the market. However, today we will focus on two specific types that are commonly used in the industry.

2 Types of Optical Filters: Explained

Let’s dive into the world of optical filters and explore their functionalities.

What are Optical Filters?

Optical filters are devices that selectively transmit light of different wavelengths, allowing only certain colors or wavelengths to pass through while blocking others. They are essential components in various optical systems, including cameras, microscopes, and spectrometers.

Type 1: Absorptive Filters

One of the types of optical filters is absorptive filters. These filters work by absorbing specific wavelengths of light while allowing others to pass through. Absorptive filters are commonly used in applications where precise control over the transmitted light spectrum is required, such as in photography and spectroscopy.

Type 2: Interference Filters

Interference filters, on the other hand, operate based on the principle of interference of light waves. These filters consist of multiple layers of thin films that reflect and transmit light at specific wavelengths. Interference filters are known for their high spectral purity and are often used in applications like fluorescence microscopy and astronomy.
