Unsurpassed holographic fidelity using "Ultimate" (tm) Plates and films
|
|
Polaris Research Group Holographic materials in both plate and film include high sensitivity and very high resolution for pulsed and continuous lasers for holographic reflection and transmission applications (typical ~7000 lines/mm to ~10,000 lines/mm for “Ultimate Ultrafine 8 nm”.
Sensitivity for our most popular product, “Ultimate Ultrafine 8 nm”, is a remarkable 100-200 µJ/cm2. This material has tremendously better resolution and contrast than the former familiar 8E75HD Agfa material for continuous lasers.
This means only a 2-4 second exposure is required on 4” X 5” (10.2 X 12.7cm) Denisyuk hologram using a 10mW HeNe laser.
For reflection holography, factory pre-swelled plates can be purchased, to obtain instant color control or non-pre-swelled for mastering applications. Color pre-shifts and spectral sensitivities can be specified. In all cases, washing, sensitizing, latensification, hardening or other laborious pre-treatments often necessary for other manufacturer’s materials are not required at all. Alternatively, conventional color control techniques may be used as well.

Ultimate 08nm and Ultimate 15nm Holographic material Ultimate 08nm
Product description: | Ultimate 08nm is an very high resolution holographic silver halide photoemulsion which has been designed to meet most requirements of holographers. The grain is so fine (05-08nm) that all colors can be recorded inside without any diffusion. Despite this, the sensitivity is very high, much higher than concurent emulsion with comparable grain size. The material can be sensitize to any laser line, including now the ruby laser (694nm), to produce any monochromatic holograms, while using a strong safelight in the laboratory, for a comfortable work. Both transmission and reflection holograms can be recorded, with a perfect noise free rendition. The diffraction efficiency remains always very high, much higher than on usual materials, even for Denisyuk or other weak contrasted records (1:10), and even when 3 wavelengths are used simultaneously. The panchromatic applications of this material, demonstrated for the first time worldwide in 2000, remains until now absolutly unsurpassed. | | Color Sensitivity | at any visible wavelength, depending the dye used | | Grain size | 05-08nm | | Resolution | >10000 lines/mm | | Recommended Exposure Energy | 90-200µJ/cm² (standart hologram) -300µJ/cm² (master- wide bandwidth) | | Diffraction efficiency | up to 98% (mirors) | | Spectral sensitivity | specialized dyes for 440nm / 440-490nm/ 510-540nm / 615-660nm /660-710nm /Holographic panchromatic continuous and pulsed (new) /Lippmann isopanchromatic | | Base | glass plates (3mm) - triacetate 190µm | | Preshift | 70nm preshift as standart on red sensitive material.

Ultimate 15nm
Product description: | Ultimate 15nm is a high speed holographic silver halide photoemulsion which has been designed for all applications with red laser, and many applications with green laser (for example pulsed reflexion, but not continuous Denisyuk). The grain is still fine (15nm), but the sensitivity is higher than ultimate 08. The material can be sensitize almost any laser line (in test now for Ruby laser) to produce monochromatic holograms, while using a strong safelight in the laboratory, for a comfortable work. Both transmission and reflection holograms can be recorded, with a very low noise rendition. The diffraction efficiency remains always very high, much higher than on usual materials, even for Denisyuk or other weak contrasted records (1:10), when a monochromatic wavelength is used. | | Color Sensitivity | at any visible wavelength, depending the dye used | | Grain size | 15nm | | Resolution | >7000 lines/mm | | Recommended Exposure Energy | 75-100µJ/cm² (standart hologram) -120µJ/cm² (master- wide bandwidth) | | Diffraction efficiency | up to 95% (mirors) | | Spectral sensitivity | specialized dyes for 510-540nm / 615-660nm /660-710nm (soon) | | Base | glass plates (3mm) - triacetate 190µm | | Preshift | 70nm preshift as standart on red sensitive material.
