RVM-14 C-Mount Housing Kit (Astronomy Kit)

The RVM-14 C-mount monocular housing is billet machined from 7075 aircraft-grade aluminum and designed to handle challenging real-world environments. The housing design accepts standard mil-spec PVS-14 eyepieces and C-mount objective lenses.

The monocular features a side mounting area to accept PVS-14 accessories and mounts with a standard ¼-20 thread. Two monos can also be attached to a bridge mount (RVM-14 Bridge) in a binocular configuration with the small dovetail incorporated into the top of the housing, or the dovetail can be used with the RVM-14 Arm for single mono use. Both the Arm and Bridge are articulating to lay back against the helmet when in the stowed position.

The monocular design features a rotary switch that doubles as gain adjustment. The switch initially turns the tube on at full brightness, then dims the MX-11769 image intensifier tube as the knob is rotated further. The unit includes an onboard infrared illuminator activated by a push button switch on the front of the unit. A protective fence surrounds the button to prevent accidental activation. Indicators on the edge of the viewing area show if the IR LED is actively on or if the unit detects a low battery.

The weight of the unit with standard mil-spec eyepiece and a CR123 battery is 250 grams. The total weight of the unit will depend on what C-mount lens is installed. The approximate battery life at room temperature is 75 hours. The monocular ships with a standard RVM-14 battery cap and lanyard and also a low-profile, flat-top battery cap for astronomy adapter use.

The monocular is available in Flat Black. Its components are media blasted to give a non-reflective matte finish and then black anodized for durability. 

NOTE: An extra battery cap is sent with this mono that is flat, as some c-mount objective lenses have an over-hang that the button on the standard lanyard can get in the way of and prevent the lens from seating fully.

SPECIFICATIONS:

OPERATING INSTRUCTIONS:

• Assemble the monoculars just like a PVS-14
• The rotary switch turns on at full brightness then functions as a gain knob to dim the unit as you rotate further.
• The IR LED is controlled by the push button switch in the front.
• The indicator in the viewing area glows steadily if the IR LED is on, or flashes to indicate a low battery.  If the IR LED is on and a low battery is sensed, the user will see the indicator staying on but pulsing brighter and dimmer.
• To install the Bridge or Arm onto the RVM-14 make sure the locking screw is fully backed out.  Slide the shoe onto the dovetail until it stops, and tighten the locking screw to lock it in.  Loosen the locking screw knob fully to remove.
