The Swift SM91 Advanced Modular Stereo Microscope is a 'student-proof' model that provides versatility. The head can be swapped out for other optional heads, making this microscope budget-friendly now and in the future. This feature, along with the microscope's durable 'student-proof' nature and the limited lifetime warranty, make the SM91 a smart choice for schools and other institutions.
When it comes to the aforementioned 'student-proof' features, these microscopes are built to stand up to daily abuse. The locked-on eyepieces ensure that they stay where they belong - on the microscope. The 'C-wrench' gives the teacher sole control over focus tension, while the 'slip-clutch' system prevents overfocusing, and thus damage to the focusing mechanism. The cord-hanger ensures safe and hassle-free cord storage, while the synthetic gear lubricant provides smooth operation of all gears over a wide range of temperatures.
The SM91 is illuminated via two light sources, the top light and a variable transbase LED with dimmer switch. The microscope's 1x and 2x objectives provide detailed and accurate views of specimens. The eyepieces of the SM91 can each be adjusted to the user's interpupillary distance. These widefield, 10xd, 23mm eyepieces are also inclined at a 45° angle for ergonomic viewing. Additionally, eye-guards provide eyeglass wearers comfortable viewing. Other highlights of the microscope include a smooth-moving turret, a 360° rotatable head, and an extra large 90mm diameter specimen stage, with clips for holding specimens in place.
