Holography Plates and Supplies![]()
PHR63 Pack of 6 PHGKIT Chemical Development Packets Application Idea See the Creating Holograms ![]() Please Wait Features
This page contains Thorlabs' selection of holography plates and developer chemical packets. In addition, we offer a kit that includes plates, developer chemical packets, a laser source, and accessories that are ideal for creating reflection holograms. Holography Plates Chemicals for Hologram Development Thorlabs sells lasers, mounts, and optics ideal for making holograms. Recommended options for beginning holography are listed on the Creating Holograms tab. Additional options for laser sources, optics, and accessories are listed on the Other Components tab. For our red holography plates, we also offer a preselected assortment of items that can be purchased with one click (see the last two product groupings on this page). PHG63 Green-Sensitive Holography Plate Graphs
PHR63 Red-Sensitive Holography Plate GraphsThis tutorial offers suggestions for making reflection holograms. While the plates offered by Thorlabs are capable of producing both types of holograms, the plates are optimized for creating reflection holograms. Introduction Creating Holograms Reflection Holograms Figure 1 shows the setup we used to create our holograms. To minimize reflections from the optical table, we placed coins on a matte black surface (e.g., a small piece of TB4 black hardboard). Since holography can suffer greatly from vibrations, it may be beneficial to use our vibration isolation plates (S913B or S913A) along with a sheet of sorbothane (SB12B or SB12A). The light emanating from the fiber tip can be aimed at the plate using our SL20 articulated base. A complete parts list is shown in the table below. In this configuration, the plate is placed directly next to the object to be imaged, while the laser beam is incident on the other side of the plate. As an initial object, we recommend using coins or another reflective object. In this configuration, the beam directly incident on the plate forms the reference beam, while the beam reflected off of the object interferes with this reference beam to form the interference pattern on the holography plate.
The entire setup should be in a fairly dark room, and any light should be blocked from reaching the holography setup. Set up the object and the laser. Turn on the laser, and adjust the beam direction until it covers the objects. Turn off the laser, and place the holographic plate in position with the emulsion (sticky) side of the plate touching the objects. Then turn on the laser with the "enable" button for between 5 to 10 seconds. Disable the laser output, and process the plate. Developing Holograms Viewing Reflection Holograms The reflection hologram can also be viewed with a point source located so that the light transmits through the plate. Again, the angle of the light source and the viewer will need to be adjusted. The results are shown in Figure 3. Transmission holograms must be illuminated with the laser used to expose the plates in order for the image to be visible. ![]() Click to Enlarge Figure 2: A reflection hologram viewed by reflecting light off of the plate. ![]() Click to Enlarge Figure 3: A reflection hologram viewed by transmitting light through the plate. *More information on the theory and history of holograms may be found in Hecht, Eugene, Optics, 4th Ed., Addison Wesley, 2002. The Creating Holograms tab and the Complete Red Reflection Hologram Kit section below suggest a set of components that can be utilized to create reflection holograms. This tab has additional Thorlabs components that can be utilized in the creation of holograms. Thorlabs stocks many other components that could be useful for holography. Our tech support staff is available to answer any questions you may have about configuring a system to record holograms. Light Sources for Red-Sensitive PlatesIn order to easily create holograms, the laser must have a large enough beam to fill the holographic plate. Since a diverging beam is acceptable, we recommend using our fiber-coupled laser source, since the light will spread broadly from the fiber tip and fill the plate if placed at a sufficient distance. If a collimated laser source is used, we recommend using a lens to diverge the light.
Light Sources for Green-Sensitive PlatesFor our green-sensitive holography plates, Thorlabs offers two options. A lens is required to diverge the light so that the laser beam fills the plate.
Mounts for Holography PlatesFor larger objects where it would be more desirable to have the plate mounted vertically, Thorlabs offers several mounts. For the most stable mounting of the holography plate, the SFH3 filter holder can be used; however, this decreases the clear aperture of the plate to 1.64" (41.7 mm) in the horizontal direction. Our CH2B cylindrical lens mount will allow the entire clear aperture of the plate to be exposed, but the plate may not be as stable, leading to reduced hologram quality. To increase the stability, two CH2B mounts may be used.

The PHG63 green-sensitive holography plates are designed to be exposed with green laser light near 532 nm. While they can be used for both reflection and transmission holograms, they are ideal for reflection holograms. For details on techniques to make reflection holograms, please see the Creating Holograms tab above. We recommend storing these plates in a refrigerator; the plates have an 18 month shelf life at 4 °C (39.2 °F) and are sold in a pack of 6. In addition to the plates, Thorlabs also offers the PHGKIT chemical developer packets. The chemicals come in seven packets and must be mixed with distilled or deionized water. Three 1 liter glass or plastic bottles, 2 small (just large enough to hold the holographic plate) glass or plastic trays, and 2 large (capable of holding 1 liter) plastic or glass trays are required for mixing the chemicals and must be supplied by the user. The mixed chemicals may be stored in tightly sealed bottles and will last for several months. The chemicals should be carefully labeled as not safe for consumption and should not be stored near food. Please note that the PHGKIT is classified as a dangerous good in some countries. Depending on the delivery location, this item may need to be shipped separately from the rest of your order at an additional charge. Please contact our sales department if there are questions or concerns when placing an order for this item. ![]()
