Custom Blended Liquids
Please contact us prior to ordering custom blended liquids to confirm pricing.
We also recommend that you complete our Optical Liquid Tech Form.
Immersion Liquid formulations are custom blended at 589.3 nm and 25°C to an accuracy of ±0.0005 in the range of nD 1.293 – 1.700.
Laser Liquids formulations are custom blended at 589.3 nm and 25°C to an accuracy of ±0.0002 in the range of nD 1.2930 – 1.6300.
Do you require deviations from these standard specifications? We can provide changes in wavelength, temperature, and accuracy for an additional cost. It is also recommended that you complete our Optical Liquid Tech Form before proceeding with your order. This will help ensure there is no confusion over what you need.
Applications: Detect striae in glass; Index Matching and Optical Coupling; Polariscopic immersion technique.
Fill hollow prisms; Make optical connections, BK-7, fused silica and other glass types; Artistic projects
All of the Immersion Liquid Specials are colorless except for code 50BN, which has a slight yellow tint.
