The Forward DFA75 is a digital night vision device designed for fast and easy conversion of a day scope into a digital night vision scope. To install the Forward DFA75 onto the front optical bell of a day telescopic sight, specially designed Cover Ring Adaptors (bought separately), are used. The Forward DFA75 will fit most day scopes.
The adaptor is designed to be permanently attached to the optical bell of a day scope. The Quick Release mount on this allows the Forward DFA75 to be quickly installed in front of the scope for night time shooting. The device uses a highly sensitive Sony CCD array; the image transmitted to the high resolution OLED display (640x480 pixels) is contrasty, crisp and saturated. Thanks to the use of an OLED display the Forward DFA75 can be used within a wide temperature range from -20 °C to +50 °C.
The Forward DFA75 features variable brightness and contrast (from 0 to 20) plus sensitivity enhancement settings. It allows the image to be adjusted to optimise performance for different operating conditions. The Forward DFA is equipped with a removable, eyesafe IR Laser Illuminator (915nm wavelength, safety class 1) which functions in the 'invisible' IR range. The illuminator features IR beam focusing (from spot to flood) and three-step power adjustment.
The main menu includes various functions such as: set-up, check and adjustment of the aiming point and 'Horizon' adjustment function. Icons on the data panel show operational status of the device (active functions, low battery indicator, etc)
The Forward DFA75 features a Video Out allowing attchment of an external DVR or monitor. The output video signal standard can be changed in the main menu (from PAL to NTSC). This product operates on four AA Alkaline/Lithium/Rechargeable batteries, but can also be powered by an external power pack - either the EPS3 or EPS5. Basic control functions (switching on/off of the device and the IR Illuminator, activation of 'SumLight™' software) can be performed via the included programmable wireless remote control.
The unit is optimised for performance on most day scopes with a magnification of 2-7x (dependent on individual scope design/performance). Whilst the unit may work with higher magnification, the Menu may not be visible or the resolution may break down to an unacceptable level (by zooming you are magnifying the individual pixels of the OLED screen).
The attachment is designed for professional and amateur use including hunting, observation, security and law enforcement.
Adapters with a set of reducing rings of various diameters are used to mount the Forward DFA on the housing of a day sight's lens. The size of the rings is determined by the outer diameter of the housing of the lens of your day sight.
Retaining the point of impact
Due to the calibrated power of 1x, the Forward DFA retains the point of impact when mounted on a day sight. This prevents displacement of reticle image relative to the point of aiming when mounting the attachment in front of the riflescope, as well as when inclining the attachment relative its optical axis.
Advantages of design
When shooting with an attachment coupled with an optical sight, some important operational characteristics of day optics are preserved, namely: longer eye relief (compared to conventional NV riflescopes), customary reticle, variable magnification.
Wide operating temperature range
Ability to operate in normal mode at sub-zero temperatures is due to the use of a frost-resistant OLED display featuring fast response and provides crisp image when observing dynamic object.
Most of NV riflescopes have a fixed magnification not exceeding 6x. Coupled with a day sight, the attachment provides a tool for night shooting, ensuring variable magnification, as well as highest possible magnification.
Invisible laser IR illuminator
The Forward is outfitted with built-in IR Laser Illuminator featuring three-step power adjustment. Complying with Class 1 laser safety, the laser IR Illuminator operates in the covert IR range (915 nm), invisible to the unaided human eye.
User friendly interface
Running status of unit's operation is displayed in the form of alphabetic and numeral characters and color icons. Graphics are permanently visible on a dedicated panel at the bottom of the display without overlapping the image observed.
Wireless remote control
The wireless remote control allows you to turn/off the attachment, the built-in IR Illuminator and enhanced sensitivity function (SumLight™) without using the main controls.
External power supply
Operating time can be significantly extended by using high-capacity external power supply units attached to the Forward via an external power jack. During continued use in freezing weather, the external power supply units can be stored under the clothes.
The Forward is equipped with a Video Out jack enabling real time video recording with the use of external recording equipment.
