The Regula 4305DMH is an advanced second line forensic spectral comparator with 21 integrated light sources, a digital 4Mpx camera, 100x on screen magnification.  This system captures, stores and compares high resolution images for forensic examination.

The device has a spacious working area over the object stage, clamps for fixing examined documents and a special shield protecting from harmful effects of ultraviolet radiation.

The device is operated via the front panel with control buttons or/and Regula forensic studio software. The control buttons are responsible for the activation of light sources and adjustment of camera parameters in different examination modes. The latter are displayed on the LCD display.

Video spectral comparator Regula 4305DMH is equipped with a torch and a modified 10x magnifier Regula 1003M with two white light sources. The front panel of the device has a port for connection of a UV bottom lighter, three available USB-2.0 ports — for additional external devices, such as a spectral luminescent magnifier Regula 4147 used in anti-Stokes examination, thermostage Regula 4168 or a magneto-optical visualizer Regula 4197.

Features

• Magnification up to 200x (for 30 inch monitor)
• Connection interface — USB 3.0
• Protective shields against harmful UV radiation
• Big size/thick documents examination option
