Visual electrophysiology and psychophysics on a cart
The Profile System is a versatile, cart-based platform for the complete range of electrophysiology and psychophysical tests offered by Diagnosys. Depending on your needs, the cart can be configured for flash-based testing with the ColorDome® or ColorFlash, or for pattern-based testing with the LI-LCD Monitor or Envoy. Each system includes a high-performance amplifier, computer, and our robust Espion® software with pre-loaded protocols to support every test.
Compatible stimulators:
O.R. cart for supine testing
A mobile cart can be equipped with a ColorDome mounted on an operating room arm, making it easy to wheel directly into surgical settings or position comfortably for wheelchair-bound patients.


Two-cart profile system
For testing with both the ColorDome and LI-LCD Monitor, the Profile System can be configured as a two-cart setup: the primary cart houses the ColorDome along with the computer and amplifier, while the ancillary cart supports the LCD monitor. Both are operated seamlessly through a single computer–amplifier combination for fully integrated testing.

Operator-patient layout
Designed for ease of use, you can operate the computer from the back of the cart while the patient sits opposite, positioned for testing.
