Immersion Oil
Very important component. Mostly used for oil immersion objectives, the refractive index should match the RI of glass from the coverslip and the objectives used. Different types or grades are available A (Low viscosity), B (high viscosity), N, F, FF (for fluorescence) etc... as well as different viscosity. Because the refractive index (and viscosity) vary with the temperature you should buy immersion oil matching the room temperature. Usually 23C but you could also need 30C and 37C.
