- https://www.opto-e.com/basics/reflection-transmission-and-coatings
- Optical coatings – one or more thin layers of material deposited on the lens surface – are the typical solution: a few microns of material can dramatically improve image quality, lowering reflection and improving transmission. Transmission depends considerably on the light wavelength: different kind of glasses and coatings helps to improve ...

- The Wavelength is varied from 660nm (a) to 470nm (b) Example 2: White Light vs. Monochromatic MTF In Figure 4, the same lens is used at the same working distance and f/#. Figure 4a is using white light, and Figure 4b is using 470nm illumination. In Figure 4a, all of the performance is at 50% or below at the Nyquist limit.

Wavelength and optical performance - Opto Engineering
- https://www.opto-e.com/basics/wavelength-and-optical-performance
- Wavelength and optical performance. The performance of an optical system is influenced by the wavelength of the light used. When designing an optical system, you can choose whether to optimize it on a single wavelength or on a range of wavelengths. The wider the desired wavelength range, the more complex the optical system must be in order to correct chromatic …
Internal Cut Filter Transmission - Kolari Vision
- https://kolarivision.com/articles/internal-cut-filter-transmission/
- If two filters are stacked, the transmission can be determined by mutliplying the transmission values of both filters for each wavelength. For example, if one filter has 50% transmission at 600nm, and another has 20% transmission, the combined transmission at 600nm would be 0.50 x 0.20 = .10, or 10%. Nikon
The Correct Material for Infrared (IR) Applications
- https://www.edmundoptics.com/knowledge-center/application-notes/optics/the-correct-material-for-infrared-applications/
- Transmission. The foremost attribute defining any material is transmission. Transmission is a measure of throughput and is given as a percentage of the incident light. IR materials are usually opaque in the visible while visible materials are usually opaque in the IR; in other words, they exhibit nearly 0% transmission in those wavelength regions.
