China Wholesale photoelectric effect Pricelist – LADP-15 Apparatus for Determining Planck’s Constant(Software Optional) – Labor

Short Description:

Based on the basic model (LCP-7), LCP-8 is a complete model that includes conventional silver salt holographic plates with related accessories. Apart from the experiments that can be conducted with LCP-7, LCP-8 can be used to conduct more experiments in a darkroom with the aid of a tri-color safety lamp for transmissive and reflective hologram recording, including two- and three-dimensional hologram, one- and two-step rainbow hologram, image plane rainbow hologram, holographic reproduction, holographic device fabrication (transmissive or reflective holographic grating, and holographic lens), and holographic storage.

Note: a stainless steel optical table or breadboard (1200mmx600 mm x 600 mm) with optimal damping is needed for use with this kit
