TMF can provide several variations in coating design for the beamsplitting surface, ranging from dielectric multilayer systems to single layer metallic  coatings. The transmission / reflectance ratio and the efficiency specified will determine the coating used.

Metal (50/50 Ratio)

Advantages

  • Good wavelength neutrality
  • Wide range of T/R ratio
  • Large sizes, up to 1500 x 2500mm

Disadvantages

  • Can have high absorption factor

 

Metal (50/50 Ratio)
 

Dielectric (50/50 Ratio)

Advantages

  • Low absorption
  • T/R ratio can be designed to cover 2-98% over a waveband 400- 1500nm
  • Ideally suited for single wavelength application

Disadvantages

  • Ratio is wavelength dependent.
  • Can produce polarisation effect above incident angles of 20 degrees

Applications

  • Laser beamsplitters
  • Sighting systems

 

Dielectric (50/50 Ratio)
 

Neutral Titanium Oxide (65/35 Ratio)

Advantages

  • Good neutrality for T/R ratios up to 65 / 35
  • Non absorbing
  • Large size availability

Disadvantages

  • Maximum T/R ratio is 65 / 35

Applications

  • Ideally suited for simulator projection, e.g. aircraft simulators, auto prompting, teleprompting and video systems
  • Head up displays
