Mega-9 Optical produces high performance optical filters in large volumes or single-piece quantities for all requirements of spectral light measurement and control.
2. The optical filter of claim 1, wherein one of the first and second optical elements is tunable to change the corresponding first or second reflection wavelength. 3. The optical filter of claim 2 further includes a compression device that axially compresses at least one of the first and second optical elements, wherein at least one of the respective first and second reflective elements is disposed along an axial direction of the respective first and second optical elements. 4. The optical filter of claim 2 further includes: a first compressing device for axially compressing at least the first optical element to tune the first reflective element, responsive to a displacement signal, wherein the first reflective element is disposed axially along the first optical element; and a displacement sensor, responsive to the compression of the first optical element, for providing the displacement signal indicative of the change in the displacement of the first optical element. 24. The optical filter of claim 22, wherein the first reflection wavelength and the second reflection wavelength are substantially aligned to reflect a portion of the aligned wavelength bands to an output port. 25. The optical filter of claim 22, wherein one of the first and second filter functions comprises one of a Gaussian, rectangular and ramp shape. 26. The optical filter of claim 22, wherein one of the first and second reflective elements is fully apodized and the other of the first and second reflective elements is partially apodized. 27. The optical filter of claim 22, wherein the first reflection wavelength is offset a predetermined spacing from the second reflection wavelength. 28. The optical filter of claim 22, wherein at least one of the first and second reflective elements includes a Bragg grating.
