6. 1. Optical block overview
・The light source is composed of a blue LED, the red LED and the
laser unit (LD).
LD is formed by 30 blue light laser diodes and mountain type
collimate lens.
・The blue laser light from LD is equalized with a diffusion board,
after being condensed by a relay lens 1-2.
Then, it reflects with a G-Transmissive Dichroic mirror, and enters
into a phosphor wheel.
・
It is changed into a green light with a phosphor wheel, it is changed
into a parallel light by P-Collimate lens1-3, and enters into a rod
integrator.
・The light of each LED, changes emission light into parallel light by
each collimate lens, lets each dichroic mirror and each relay lens
pass, and enters into a rod integrator.
