Attention! You can customise this product to your needs.

8MID40-70 Motorized Iris Diaphragm Mount was developed due to interest in our previously presented motorized iris 8MID98-4. Motorized Iris Diaphragm is designed for our small diaphragm family. Unfortunately it is impossible to interchange iris diaphragms at home since every diaphramg has its own adapter ring and requires calibration.

Temperature limits:
AR - leaves with AR coating, for temperatures up to 180 °C
N - springsteel, black finished, for temperatures up to 250 °C
H - stainless steel, for temperatures up to 400 °C
