The SPECT scan, short for single photon emission tomography perfusion scan, is a procedure that gives a three-dimensional picture of the function (assessed by blood flow) in the heart and/or lungs. During the SPECT scan, you will have an injection into a vein in your arm of a small amount of radioactive material.

Its leading edge design assures the ultimate in clarity (with illumination and image). It accommodates practitioners with smaller interpupillary distances, generally 49 to 74 mm.

Spectral transmittance meter is an electric equipment designed to measure light wavelength transmission in all types of lens material. It provides an easy way for the user to understand the differences between multi-coated and UV protected sunglasses. It enables determinations of UV transmission as well as visible light wavelength.
