Photographer's Formulary 602 Holography Developer HD-602 was formulated by Hans Bjelkhagen of Lasergruppen Holovision AB, Stockholm, Sweden.
It is a developer for reflection holograms in particular; made for Agfa Holotest 8 E7 5HD material. The developer works well for Denisyuk type reflection holograms using both HE-NE or Krypton CW lasers or pulsed ruby lasers.
The exposure depends on the laser used but is around 100 uJ/cm2.
HD-602 works very well giving a high signal-to-noise ratio and high diffraction efficiency. The developer is completely stable as long as Part A and Part B are not mixed, and remains stable after being mixed for several weeks.
One liter of mixed developer can be used to do up to 100 - 4 x 5" plates.
A reversal "Pyrochrome Bleach" is included in this kit. Chemicals will make 1 liter of three solutions.
