Thermoplastic Holography

Fujinon

Developed the FH2AR holographic camera (1976) and the FHLXII vibration analysis system.

The FH2AR combined a thermoplastic holography system with an Argon laser.

The FHLXII integrated a 2W or 4W Argon laser with an optical table, and could use either 6x9cm plates or a thermoplastic recording system with an 2.5" by 2.5" aperture. The system had an illuminated area up to 1m by 1m across and 3m deep.

Newport Research Corp.

Built the good old HC-300.

The plates went out of production around 1997, but I was recently contacted by Robert Nichols from Sterling Resale Optics who wrote

i saw your website on TP holography. if you know of anyone looking for HC-301 thermoplastic plates by NRC, point them to www.sro-optics.com under "misc"

Note that I have no personal experience of either the company or of the particular plate involved.

Rottenkolber Holo-System GmbH

Produced a variety of holographic systems for general use and specific applications. Several could be fitted with the "PT-Holo-instant-picture" cameras, allowing a series of holograms to be made on PT-1000 or PT-1000Hs photothermoplastic film (made by Kalle ?) in 35mm format.

One system, the HIK 1000-FE, used a 700 mW Argon laser and had a working area of 1m.

Steinbichler

Currently sell the TPC 200 system, which allows the recording of 50x30 mm holograms on 30m rolls of 35mm Kalle PT 1000 S film. This has a sensitivity of around 5 erg/cm2 and a usable spectral response from 350nm to 700nm. The film's optimum spatial frequency is around 850 mm-1.

The development time is quoted as <1s, with an 8s cycle time between successive holograms; there doesn't seem to be any facility for erasing but then with a 600 exposure roll there's less need to re-use the medium.

The company also built a system for the Fluid Science lab on the International Space Station (Columbus facility).

Tavex

Produce a thermoplastic holography system. The exposed area is 32mm by 32mm and each plate should last 500-3000 exposure cycles. The material is sensitive across the 400-800nm region and has an optimum resolution of 350-1000 lp/mm.

Ultra-Res

Have developed a series of thermoplastic holography systems.The media use a 35mm slide format and have 1500 lp/mm resolution. Originally only lasted 5-10 shots (but was MUCH cheaper than Newport plates).

Ultra-Res Corp. is part of ACDS.
