  1. Optical Filter Wavefront Distortion: Out-Of-Band To In-Band Predictions 8/28/2023

    This paper explores predicting accurate in-band wavefront error of an optical filter using out-of-band measurements due to wavelength and angle variations.

  2. Designing Optical Filters For Earth Observation And Satcom 4/4/2023

    Discover how the evolution of satellite technology, driven by the rise of private space programs, transforms earth observation and communications, facilitated by advanced spectral filters.

  3. How Custom Filters Can Optimize Instrument Performance 1/9/2023

    Different Raman devices have different optical filtration needs as well as competing technical demands. 

  4. More Signal, Less Background: Improving Signal To Noise Ratio 11/28/2022

    The path to improving signal-to-noise ratio - the ratio of the power of signal (desired input) to the power of background noise (undesired input) - is to reduce the power of the noise – less background.

  5. Using Optical Filters To Measure Earth From A Different Perspective 9/19/2022

    Explore how optical filters revolutionize Earth observation, enhancing our understanding of natural phenomena and driving the commercialization of space exploration.

  6. How To Enhance Optical Blocking Using Multiple Filters 8/10/2022

    Any background light that reaches the detector of an optical system can greatly compromise signal-to-noise ratio. Using more than one blocking filter is a solution that requires careful consideration.

  7. Filter Specs Vs. Functional Specs – The Pitfall Of Double Margining 6/13/2022

    Wavelength “padding” can result in over- or under-margining of transmission/blocking wavelengths. This leads to a more expensive solution with compromised performance.
