This page describes the KMS310RT (infinity K2 IND) in detail.  Effort was started in effort to better repair them

The auto-focus and camera sync features seem to add considerable complexity.  I don't care about auto-focus and am unsure if I need the video sync feature (I should be able to deal with it through camera registers).  Unfortunately, these add a considerable number of mirrors etc that need to be clean

====== Main circuit board ======

Has an FPGA, presumably for auto-focus logic

{{:mcmaster:tech_inst:kms310rt:board_sticker.jpg?300}}

{{:mcmaster:tech_inst:kms310rt:board_no_sticker.jpg?300}}

Chips:
  * 74HC14
  * MAXIM MAX681 5V to +/-10V converter
  * ALTERA EPM5128 FPGA
  * NAT SEMI LM1881 VIDEO SYNC SEPARATOR

====== Defective optic: mirror ======

{{:mcmaster:tech_inst:kms310rt:defect_area.jpg?300}}
{{:mcmaster:tech_inst:kms310rt:defect.jpg?300}}

During removal additional damage was sustained/noticed.  Its possible the original white stuff (mostly?) comes off.  Regardless, this needs to be replaced

====== Defective optic: diffusor? ======

Schematic: L2

{{:mcmaster:tech_inst:kms310rt:diffusor_btm.jpg?300}}

{{:mcmaster:tech_inst:kms310rt:diffusor_surface.jpg?300}}

Above: surface irregularities.  These show up on microscope images

I think this is supposed to be a diffuser to make lamp illumination more even.  Unfortunately, the surface has warped leading to sharp irregularities in the final images
