T-G2P11 - GRIN Lens for Imaging, Ø0.5 mm, L = 1.883 mm, WD = 0.20 mm (Water and Dry), NA = 0.486, AR Coating: 515 - 670 nm and 900 - 1100 nm
Product Drawing
- Ideal for Multiphoton Imaging
- Ø0.5 mm and 1.833 mm Long
- Working Distance:
- 0.20 mm on Sample Side (Water Immersion)
- 0.20 mm on Objective Side (Dry)
- 0.486 Numerical Aperture in Water
This GRIN lens features a 0.20 mm working distance on both the sample and the objective side. It is designed to minimize losses for excitation wavelengths from 900 - 1100 nm and emission wavelengths from 515 - 670 nm, which is useful for eGFP and eYFP. At 0.5 mm in diameter and 1.883 mm in length, this GRIN lens provides a large collection angle due to a numerical aperture of 0.486 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.
