Photoelastic Modulator Options

Please contact us if you have questions about the following Photoelastic Modulator Options

Antireflective Coatings (ARC)

Antireflective coatings are used to address modulated interference effects and to reduce reflection.  For more information on this topic, please read our article on Modulated Interference:
Modulated Interference Effects in Photoelastic Modulators

Standard

  • ARC-1, 632.8nm on I/FS50
  • ARC-2, 450-650nm on I/FS50
  • ARC-3, 3-12μm on II/ZS50
  • ARC-4,  3-12μm on II/ZS37
  • ARC-5, 8-12μm on II/ZS50
  • ARC-6, 8-12μm on II/ZS37
  • ARC-7, 633-1000nm on I/FS50
  • ARC-8, 800nm on I/FS50

Custom

Please Contact us about your custom antireflective coating requirements.

Non-Interference Option (NIO)

The NIO option is an alternative to an AR coating for addressing modulated interference.  The NIO option slightly wedges the optic to reduce modulated interference effects.  For more information on this topic, please read our article on Modulated Interference:
Modulated Interference Effects in Photoelastic Modulators

  • NIO-1, standard on I/FS50
  • NIO-2, custom on other Series I optics

 

Magnetic Field Compatible (MFC)

This option replaces all of the ferromagnetic material in the optical head and extends the length of the cables from the optical head to the electronic head.

Special Frequency Option (SFO)

Contact Hinds if you have a special frequency request.

Special Length Cables

Custom lengths available for Head-to-Head cables (SLHH) and Head-to-Control Cables (SLHC)

Special Calibration Option (SCO)

Special Calibration for Series II PEMs for operation in the UV to visible.

Vacuum Chamber Options (VCO and UHV)

Our standard vacuum chamber (VCO) accommodates the I/CF50 modulator for vacuum UV measurements. Inside the cross chamber a specially designed tray supports the optical assembly so that its position is secure and normal to the light beam.

Also available is a stainless steel optical enclosure for low to ultra high vacuum experiments (UHV) when placing the PEM optics inside your vacuum chamber is preferred. Flanges can also be incorporated into the PEM system if you choose to use your own chamber.  Hinds provides flanges for use in both high and low vacuum environments.
