PEM-90 Systems can be incorporated
into vacuum chambers.
Antireflective Coatings (ARC)
Antireflective coatings are used to address modulated interference effects and to reduce reflection. For more information on this topic, please click here.
• Standard
ARC-1, 632.8nm on I/FS50
ARC-2, 450-650nm on I/FS50
ARC-3, 3-12um on II/ZS50
ARC-4, 3-12um on II/ZS37
ARC-5, 9-12um on II/ZS50
ARC-6, 9-12um on II/ZS37
• Custom
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,

• 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 Head-to-Head Cable (SLHH) Universal PEM Mount (UPM) This mount allows one or two PEMs to be mounted at 0, 30, 45, 60, or 90 degrees.
Rack Mount, handles only (RMH)
Rack Mount Extension Kit, with handles (RMO)
USB Adapter (USB)
Adapts the PEM's RS-232 port for use in a USB port.
RS-232C to IEEE-488 Converter - National Instruments (GPIB-NI)
Adapts the PEM's RS-232 port for use with a GPIB port.
Special Length Controller-to-Head Cable (SLCH)
Detector Power Supply, DET-90 (DET-PS)
A universal power supply for the DET-90 line of detectors. Please note that the DET-100 line of detectors includes a power supply.
Special Calibration Option (SCO)
Special Calibration for Series II PEMs for operation in the UV to visible.
Vacuum Chamber Options (VCO)
Our standard vacuum chamber 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.
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.
