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.
5. The optical filter of claim 4, wherein the displacement sensor includes a capacitance sensor coupled to the first optical element for measuring the change in the capacitance that depends on the change in the displacement of the first optical element. 6. The optical filter of claim 1, wherein both of the first and second optical elements is tunable to change each of the respective first and second wavelengths. 7. The optical filter of claim 6 further comprising: a first compressing device for compressing axially the first element to tune the first reflective element, wherein the first reflective element is written in the longitudinal direction in the first optical element; and a second compressing device for compressing axially the second optical element to tune the second reflective element, wherein the second reflective element is written in the direction in the second optical element. 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.
