Transparent Pastel Concave Diffraction Grating - Glass Laser Hologram
$25.00
Sold Out
A diffraction grating produced in dye-sensitized gelatin. As one of my first in this medium, I did not really know what to expect, but was pleasantly surprised. The pattern is pale and transparent, but worked into a nice piece of glass. Much work remains to be done with this method, but the initial results are encouraging.
Sales of these holograms continues to fund further research at Rika Labs.
Holograms are very difficult to photograph and are much better in person. There is much more depth, dimension of color, and texture to the holographic layer that cannot be described.
Recorded in "SO-DCG" on Aug 27, 2021. Produced using powerful lasers: 488 nm and 561 nm Coherent Sapphire, and 445 nm Ahura ECDL. Beams combined prior to spatial filtering and final collimation with a telescope mirror.
Prepared with safranin-O as sensitizer, tetramethylguanidine as electron donor, with emulsion pH controlled and corrected to 9.3 with TMG formate and formic acid. Emulsion layer formed via mold coating using hydrophobic and hydrophilic silane treatments on opposite sheets of glass. Dehydrated with a series of isopropanol baths prior to final development with a heat gun.
After development and processing, the delicate holographic layer is laminated behind a thick sheet of glass. The edges are ground and beveled with a series of diamond lapping wheels, then polished on a buffer to a glossy shine. The result is a jewel-like faceted appearance and an excellent feel in the hand.
The number in the corner is for inventory tracking. It can be easily removed with an alcohol wipe. Holograms are best viewed when illuminated with light coming from a single point, such as a flashlight or spotlight.

Custom work is also available. I love making holograms, and custom orders are the most rewarding. Please contact me for details.
