cfi apochromat tirf series
The objective lens of the microscope with the highest numerical aperture (Na) , the largest chromatic correction, and the calibrated correction of temperature to eliminate spherical aberration.
Objective lens CFI Apochromate Tirf Series from Nikon has the highest Na available using standard immersion oil and cover glass. Thanks to numerical aperture which is very high, when used in TIRF (Total Internal Reflection Fluorescence), this lens gives Evanescent field which is very shallow which can only be achieved with oil immersion lenses. Apochromate lens Tishf provides chromatic correction from a wavelength of 435 nm to an extraordinary wavelength of 1064 Nm. In addition, this lens has extraordinary transmission, facilitating the ability to take pictures and trap a single molecule in the same focus field. These lenses are also very suitable for the multi-moton application .
For the first time, the temperature change correction ring has been included in the lens 60x and 100x Apochromate Oil Throves . Users can easily correct changes caused by temperature, from 23 ° C (room temperature) to 37 ° C (physiological temperature) - on refractive index of immersion oil which can cause spherical aberration.
