UNIBLITZ® shutters are electronically programmed to fire specific exposures at precise time intervals. Qbic laser system Inc offers a complete line of UNIBLITZ®  shutters for a wide variety of applications, including medical imaging, CCD and video camera, and low-level laser switching.

The UNIBLITZ® shutter is based on an electro-magnetic actuator. The shutter is actuated by applying an electronic pulse to the shutter, varying its intensity during the shutter's exposure sequence, then removing the pulse to close the shutter. All UNIBLITZ® shutters are compatible with our UNIBLITZ® shutter drive equipment, which converts line voltages to those necessary to operate the shutter.

VMM-T1 FRONT PANEL

Timer configuration is easy and straightforward using the VMM-T1. EXPOSURE and DELAY intervals are selected by simple 4-digit push wheel switches, the (+) pushbutton increments a particular digit while the (-) pushbutton decrements. The number of exposures per trigger can be selected from 1-99 via the EXP. PRESET 2-digit push wheel switch. Zero indicates continuous operation. The 5 position rotary switches select the range for each TIME SELECT push wheel grouping. LED indicators reveal shutter status at a glance, while the toggle switches easily configure the VMM-T1 for specific control functions.

VMM-T1 REAR PANEL

All main input/output functions can be accessed at the VMM-T1 rear panel, including the 115/230VAC input. Manually selectable Additionally, BNC connectors allow for quick termination of TTL command signals, FUNCTION SWITCHES A-D determine the active state of each of the BNC inputs (high or low level active). FUNCTION switch E selects HIGH/LOW status. Addressable RS-232C control is also available via the DB-9 connector. The unit's specific address is selected via the ADDRESS rotary octal switch.
