Immersion Liquid formulations are similar to Refractive Index Liquids Standards but are generally less expensive. They are custom blended at 589.3 nm and 25°C to an accuracy of ±0.0005 in the range of n_D 1.293 - 1.700. Deviations from the standard specifications are available for changes in wavelength, temperature, and accuracy at an additional cost.

Uses:

• Detect striae in glass
• Index Matching and Optical Coupling (will prevent reflection loss at the interface between two solids, lenses, or fibers)
• Polariscopic immersion technique

Immersion Liquid Specials have different formulas from the Standard Immersion Liquids and have special optical or physical properties which make them better for certain applications. They are custom blended at 5893 angstroms at 25°C to an accuracy of ±0.0005 in the range of n_D 1.4520 - 1.656. Custom changes are available in the same fashion as the regular Immersion Liquids.

Uses:

• Fill hollow prisms
• Make optical connections
• Match BK-7, Fused Silica, and other glass types
• Artistic projects

Immersion Liquid Specials codes 4550, 50350 and 50BN are virtually non-fluorescing oils. Codes OHGL and OHZB are aqueous solutions (less stable than oil based liquids). All of the Immersion Liquid Specials are colorless except for code 50BN, which has a slight yellow tint.
