  5. Lower-Cost And Faster Time-To-Market MWIR Equipment – The Right Optical Filter Is Key

    Midwave infrared (MWIR) light is important in many hardware applications, and optical filters are critical to success. Some simple practices can help avoid over-specifying filter characteristics and driving up costs.

  6. How To Specify A Filter

    In general, typical filter optical specifications will include the wavelength ranges over which to reflect and transmit light, clear aperture of the filter, the polarization state of light for non-normal angles of incidence, light coherency (laser or white light), optical beam size and cone angle of light, and more. 

  7. Solving PCR Filter Challenges For High-Performance qPCR Instruments

    qPCR instrument users need high sensitivity and pristine signal clarity to achieve numerous delicate tasks. The right combination of optical filters significantly improves this functionality.

  8. Understanding Edge Filters For Raman Spectroscopy

    Since the excitation source laser intensity is often six to eight orders of magnitude greater than the Raman scattered signal, edge pass filters are required to block the wavelength of the scattered laser beam while transmitting the wavelength shifted Raman scattered signal.
