1. Excellent infinite optical system with high resolution and perfect definition. 2. Wide field 10×/Φ22mm eyepiece, more comfortable for observation. 3. 100X water objective is available for convenient viewing. 4. Trinocular head with light distribution 100:0 (100% for eyepiece) and 80:20(80% for trinocular head and 20% for eyepiece). 5. Rackless stage is safer than traditional stage.
6. Various accessories for upgrading. (1) Quintuple turret phase contrast unit with 10X/20X/40X/100X infinite plan phase contrast objective for phase contrast and bright field observation.
