Advantages Of Using Thin Film Optical Filters
Posted: Jan 10, 2018
The world of optical filter based scientific tools depends heavily upon accuracy. The more accurate the tools better will be their performance and relevance in the respective fields in which they are applied. While the presence and impact of optical filters have been felt through decades past, it is the newest entrant in the name of Dichroic reflectors also known as thin film mirrors, that has taken the matter of device accuracy and precision to the next level.
Dichroic mirrors are characterized by the property of reflecting the unnecessary wavelengths away than by the characteristic of blocking them or allowing them to pass. More often than not, they are found behind artificial sources of light where they reflect visible light forward and let the invisible infrared light to pass out from behind. This is in sharp contrast with Dichroic filters or thin film filters that are based on their attribute of allowing wavelengths to pass than reflect the same.
Whether thin film mirrors or filters, the term thin film comes with perhaps the widest range of attributes some of which can be listed as follows…
- They are designed with phenomenal power to maximize accuracy of identification and measurement devices down to even the tiniest biological samples and more.
- The filter is extremely sturdy and can function at higher temperatures than any other optical filters these days. With astonishingly high laser damage thresholds, Dichroic reflectors mirrors can be found in the most powerful lasers of the world.
- All thanks to their sturdiness,
