Knowledge & Tips
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. 8. The optical filter of claim 1, further comprising: an optical directing device optically connected to the first and second optical elements; the optical directing device directing the light to the first reflective element, directing the first wavelength band reflected from the first reflective element to the second reflective element, and directing the second wavelength band reflected from the second reflective element to the output port of the optical directing device. 9. The optical filter of claim 8, wherein the optical directing device comprises at least one circulator. 10. The optical filter of claim 9 wherein the circulator receives the light at a first port of the circulator, directs the light to the first reflective element through a second port of the circulator, receives the first wavelength band at the second port, directs the first wavelength band to the second reflective element through a third port of the circulator, receives the second wavelength band at the third port, and directs the second wavelength band to a fourth port of the circulator. 11. The optical filter of claim 8 wherein said optical directing device comprises an optical coupler.
