Vortex also designs and manufactures custom infrared LVFs, featuring different bandwidths, sizes (e.g. to suit the user’s detector window dimensions), etc. to meet your needs. Contact the AMS Technologies filter experts today to discuss a unique customized linear variable filter, designed, specified and manufactured to your application’s requirements.

Linear VariableBandpassfilter

A unit of irradiance used in measuring the amount of power per area of absorbing surface, or per cross-sectional area of a laser beam.  Also called power density.

The pulse energy is simply the total optical energy content of a pulse.  Pulse mode is operation of a laser when the beam is intermittently on in fractions of a second.

Laser therapy, regardless of the actual laser utilized, relies upon a few key units of measurement.  These measurements help select treatment protocols and monitor the dose delivered to each patient.

The energy density expresses the total amount of energy delivered per unit area, in Joules per square centimeter (J/cm2).

A unit of radiant exposure used in measuring the amount of energy per unit area of absorbing surface or per unit area of a laser beam. Also called the dose.

Knowing the key units of laser measurement allows us to talk in a common lanagurage about the parameters to treat patients. Please contact us to receive our ebook explaining the science of lasers.

Infrared linear variable filters (LVF) are narrow band filters where the center or peak wavelength changes continuously along its length from one side to the other – and across the device’s full wavelength range. Vortex’s linear variable filters feature a narrow band profile with a “full width half maximum” (FWHM) bandwidth of 1% or 2% of peak wavelength.
