T-G2P10 - GRIN Lens for Imaging, Ø1.0 mm, L = 3.400 mm, WD = 0.25 mm (Water), NA = 0.5, AR Coating: 500 - 1000 nm
T-G2P10 - GRIN Lens for Imaging, Ø1.0 mm, L = 3.400 mm, WD = 0.25 mm (Water), NA = 0.5, AR Coating: 500 - 1000 nm
- Ideal for Widefield, Confocal, and Multiphoton Imaging
- Ø1 mm and 3.400 mm Long
- Working Distance:
- 0.25 mm on Sample Side (Water Immersion)
- 0.19 mm on Objective Side (Dry)
- 0.50 Numerical Aperture in Water
This GRIN lens features a 0.25 mm working distance on the sample side and a 0.19 mm working distance on the objective side. It has a broadband AR coating optimized for 500 - 1000 nm. Suitable for excitation wavelengths from 800 to 1000 nm, the AR coating extends down to 500 nm to reduce losses for the corresponding emission wavelengths. This range is useful for Ca2+ imaging. The lens supports widefield imaging techniques to locate the target region of interest (ROI), as well as confocal and multiphoton laser scanning of the sample. At 1.0 mm in diameter and 3.400 mm in length, the GRIN lens provides a large collection angle due to a numerical aperture of 0.50 in water.

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.
