What Is A UV Filter?
A UV blocking filter or ultraviolet optical filter prevents ultraviolet light transmission. UV filters are commonly used in photography to reduce the level of ultraviolet light that strikes the recording medium.
What Is A Dichroic Filter?
A dichroic filter, thin-film filter, or interference filter is a very accurate color filter used to selectively pass light of a small range of colors while reflecting other colors. By comparison, dichroic mirrors and dichroic reflectors tend to be characterized by the color(s) of light that they reflect, rather than the color(s) they pass.
What Is A Neutral Density Filter?
A neutral density, or ND, optical filter reduces or modifies the intensity of all wavelengths or colors of light equally, therefore providing for no changes in the hue of the color rendition. Neutral density filters can be colorless or clear, or they can be grey in tone.
How To Measure Thin, Parallel Optics
Thin, parallel optics are difficult to measure, because both front and back surfaces reflect light. Fourier- Transform Phase Shifting Interferometry can separate those reflections and provide more information than traditional methods.
Remote Sensing With LiDAR Requires Optical Filter Trade-Offs
Engineers and designers working on LiDAR applications should consider critical filter issues early on.
LiDAR And Optical Filters – Helping Autonomous Vehicles See More Clearly
The evolution of sensing and imaging systems, combined with the desire to create safer, more efficient transportation systems, is driving the development of autonomous vehicles. LiDAR is a key technology that will eventually help carry this growth through to “Level 5” autonomy.
The Right Filter Is Key To Lower-Cost And Faster Time-To-Market MWIR Equipment
Midwave (MWIR) infrared light is important in many hardware applications and optical filters are critical to success. Some simple practices can help avoid over specifying filter characteristics and driving up costs.
