www.microscopenet.com Note: When using the 40X objective, you won’t need to apply oil drop on the oil condenser. When using the 100X objective, the condenser won’t work well if no oil drop applied on the condenser. When you apply the immersion oil with the 100X objective, do not let the immersion oil to contact with the dry objective lenses (especially the 40X).
www.microscopenet.com Note: When raising the mechanical stage, do not make contact with the objective. 3) Turn the desired objective into light path. 4) Turn the annular ring disk to put the corresponding ring into light path, i.e. if you are using the 40X phase contrast objective, you should turn the disk at 40 as shown in Fig.
