Mega-9 Optical produces high performance optical filters in large volumes or single-piece quantities for all requirements of spectral light measurement and control.
1. An optical filter comprising: a first optical element including a first reflective element for receiving light and reflecting a first wavelength band of the light centered at a first reflective wavelength, the first reflective element characterized by a first reflective filter function; and a second optical element, optically connected to the first a second optical element to receive the reflected first wavelength band of the light, including a second reflective element for reflecting a second wavelength band of the light centered at a second reflection wavelength, the second reflective element characterized by a second reflective filter function, whereby at least one of the first reflective filter function and the second reflective filter function is not substantially flat over a substantial portion of the respective first or second reflective filter function, and the first wavelength band and the second wavelength band overlap spectrally. 1.
