Objective Lenses
Magnification | Immersion Medium | Designation | Numerical Aperture | Coverslip Correction | Working Distance(mm) |
---|---|---|---|---|---|
10X | Air | Plan Apo | 0.45 | 0.17 | 4 |
20X | Air | CFI Plan Apochromat VC | 0.75 | 0.17 | 1 |
40X | Air | CFI Plan Fluor | 0.75 | 0.17 | 0.72 |
60X | Oil | CFI Plan Apochromat | 1.4 | 0.17 | 0.13 |
100X | Oil | CFI Plan Apochromat VC | 1.4 | 0.17 | 0.13 |
60X WI | Water | CFI Plan Apochromat | 1.2 | 0.17 | 0.27 |
There is also a 100x 1.3 NA Plan Fluor oil objective that can be used if the PFS range turns out to be too narrow when using the 100x Plan Apo.
There is a choice of three immersion oils:
Oil | Refractive Index | For use with... | Kept in... |
---|---|---|---|
Cargille Type HF | 1.518 (at 23ºC) | Oil lenses at room temperature | Tray outside environmental chamber |
Cargille Type 37 | 1.518 (at 37°C) | Oil lenses at 37ºC | Tray inside environmental chamber |
Zeiss Immersol W | 1.334 (at 23ºC) | Water immersion lens only | Tray inside environmental chamber |
Note that Cargille Type 37 is optimal for use at 37ºC but introduces spherical aberrations when imaging beyond about 10 μm in aqueous media because it is not refractive indexed matched to water. Zeiss Immersol W in combination with the 60x WI lens might be a better choice in this case but its RI is corrected for use at room temperature and won't be correct at 37 degrees.
Lasers and emission filters
The Vox has diode or DPSS lasers that emit the following wavelengths: 405 nm, 488 nm, 561 nm and 640 nm.

Filter cubes in the microscope stand
The filter cubes below are for use when viewing your specimen down the microscope eyepieces. The filter turret must be in position 1 (EMPTY) when imaging with the spinning disc.
