The F11-10 microscope is a favourite in schools, it boasts rugged metal construction, metal focusing gear and student-proof locked-on components. The bright, sharp images are impressive for a microscope with a 0.65NA condenser leading some schools to add a 100x objective to the specification. Though we would advise a magnification of no more than 600x, achieved with an optional 60x objective.
The very attractive 1801 microscope shares the same specification as the F11-10 but has slightly better quality objectives and re-chargeable batteries.
New this year are the B-151, B-151R and B-151ALC from Optika. These microscopes are manufactured in Italy under stringent quality control standards and boast a sleek and modern look. The B-151R has re-chargeable batteries and as a first for the education market the B-151ALC features Automatic Light Control. This allows the user to set a level of light intensity that is both desirable and comfortable, this level is maintained even if the user adjusts the diaphragm or changes objective or even chooses to look at a different slide. You really need to experience this feature to understand just how much it aids your microscopy work.
