Self-check when power on, adjust the luminance brightness, to make sure the initial projection brightness standard.
Use two optical gradual coating film change the optical transmittance by changing its position combination thus obtain 0-51dB standard spot brightness.
Change the spot color using a standard color filter Ensure spot color temperature standard, can accurately stimulate specific cone cells.
Inspection strategy designed to take full consideration of different age groups, responsiveness, visual field defects and the distribution of filed the island
Test faster, clinical results more accurate.
