6. Lab requirement

1) Dark room dimension: 3m(H)*2.5m(W)*8m(L) above, or designed according to lamp size and lab size. The rotating console and detector are put in dark room. Dark room (includes wall, ceiling and floor) should be coated with dull dark paint, or be covered with black carpet or black cloth.

2) Control room: 2.5m(H)*3m(W)*3m(L). The control cabinet, computer and printer are put in control room.

3) The temperature of dark room should be controlled by air conditioner according to CIE requirement.

4) Pego will provide lab design support according to actual conditions after order confirmed.
