These uncoated GRIN lenses feature a 0.20 mm working distance on both the sample and the objective side. Each lens is 1.0 mm in diameter and ideal to be used in widefield and laser-scanned confocal imaging. The T-G1P10 lens is 3.758 mm long, while the T-G1P11 lens is 8.091 mm long. Each lens provides a large collection angle due to a numerical aperture of 0.50 in water. See the Specs tab for more details on optical properties.

Lens Handling and Care
Handling
A GRIN lens should be handled with stainless steel tweezers, preferably those with a tapered end like our TZ3 optic tweezers, and picked up by firmly grasping the side of the cylinder rather than the flat ends.
Cleaning
Use methyl alcohol as a cleaning solvent when necessary. Acetone may also be used without harm to a GRIN lens, but should be pure enough to not leave a residue on the lens surface.
Storage
For extended periods of time, a GRIN lens should be stored in a "dry box" environment. This entails the use of a desiccant or heat source to prevent humidity from leaching the lens material. For short-term storage (less than a month), the plastic box and foam packing in which the lens is shipped will provide adequate storage, provided the lens is placed securely in the built-in slot to avoid chipping or scratching from other lenses.
