Caution:  ethyl  and  isopropyl  alcohols  are  highly  flammable!  Do  not  use 
near extreme heat, arcing electrical equipment (such as space heaters) or 
open  flame!  Use  only  with  proper  ventilation.  Follow  all  safety 
instructions provided by the manufacturer of the alcohol product.

Infra-red filter removal and installation 

If  greater  near-infra-red  sensitivity  is  desired,  the  infra-red  filter  can  be  removed.  It  is 
important  to  note  that  removal  of  the  IR  filter  can  allow  debris  to  collect  on  the  CCD 
faceplate.  Please  use  every  precaution  to  avoid  contact  with  the  CCD  faceplate  and  to 
keep the camera securely mounted to the optical system or capped when not in use.

How to remove the IR filter 

 

Caution

: This procedure will cause the focus calibration to be lost. Readjustment of the 

lens back-focus will be required after reassembly 
 
Loosen the lens mount lock ring with the wrench supplied by DVC 
 
Unscrew the lens mount/filter assembly ring from the camera body and remove the lock 
ring from the lens mount ring 
 
Hold the lens cap with the pins sticking upward in one hand 
 

 

 
Lower the lens filter assembly on to the pins with the other hand
