What is Dichroic

Dichroic is a type of filter or thin-film interference filter used to manipulate the color of light. These filters are designed to selectively pass light of a specific range of colors while reflecting other colors. They work based on the principle of thin-film interference, similar to the phenomenon observed in oil films on water.

Dichroic filters are commonly used as an alternative to dyed plastics and glass when precise control over the color of light is required. Unlike traditional filters that absorb unwanted colors, dichroic filters reflect them, allowing for higher intensity light sources to be used. This makes them suitable for applications where color accuracy and brightness are crucial, such as in stage lighting, architectural lighting, photography, and various other lighting systems.

Dichroic filters can also be utilized for heat control, blocking ultraviolet (UV) and infrared (IR) radiation. They can act as soft and spread lenses, as well as for color correction purposes. Dichroic filters are widely used in a range of industries, including entertainment, retail, museums, residential and outdoor lighting, among others.

Frequently Asked Questions

Are LED Bulbs Dichroic

Dichroic bulbs are available in various types, such as halogen and LED, and they can be found with GU4, GX5.3, and Gu5.3 base types.

What Is a Dichroic Reflector

Dichroic reflectors, also referred to as cold mirrors, are frequently utilized behind a light source to redirect visible light towards the front, while permitting the passage of infrared light through the back of the fixture. This configuration enables the provision of powerful illumination while minimizing the amount of heat generated on the object being illuminated.

Does Dichroic Glass Change Color

Dichroic Glass, also referred to as color effects glass, has the ability to reflect certain colors while allowing others to pass through. This distinctive glass exhibits two distinct colors, which can vary depending on the lighting conditions.

What Are Dichroic Colors or Filters

A dichroic filter, also known as a thin-film filter or interference filter, is a highly precise color filter that is utilized to selectively transmit light within a narrow range of colors while reflecting all other colors.
