  3. Correction collar of objective (temperature, cover glass thickness)
  4. Insert filter cube into filter wheel (if not currently available)
  5. Check position of ND filters in front of 405, argon and 561 laser heads (probably the up position)

    2. lamda plate and nd filter positions
    3. Angle and collimation of laser (spot on roof)


Check laser collimation

  1. Focus on sample using transmitted or epi light
  2. Open environmental chamber roof and push transmitted light arm to back position (check CO2 is off)
  3. Adjust laser angle offset from software to directly upward, depending on cube should be approx 3200
  4. Adjust point on roof
    1. loosen collimator lock screw
    2. micrometer screw for y-direction
    3. software offset for x-direction
    4. collimator push/pull for spot size (small round spot with concentric circles around)
