Why Everyone Loves It

60× – 120× Zoom Slider – sweep smoothly through magnifications with a thumb-push and hear a reassuring click at each detent, so kids won’t overshoot their target.
Fine-Focus Wheel – a grippy, knurled dial that lets adults dial-in razor-sharp detail (≈ 90 ° travel) without losing the subject.
Brilliant LED Illumination – a built-in white SMD LED lights specimens from below, revealing colour, texture, and structure you can’t see with the naked eye.
Pocket-Sized Powerhouse – weighs about the same as a chocolate bar (≈ 60 g) and slips easily into your backpack, toolbox, or lab coat.
Built-In Ruler Base – measure pollen grains, textile threads, or insect legs instantly with moulded 0–25 mm and 0–1 in scales.
Smartphone Adapter – Carson’s MM-310 clip to capture stunning micro-photos and share your discoveries online.

Perfect For…

Kids & STEM Learners – explore leaf veins, rock crystals, or salt grains right at the kitchen table.
Hobbyists – check coin mint marks, stamp perforations, or jewellery settings in seconds.
Field & Pro-Lite Work – inspect solder joints, textile fibres, plant pests, or forensic samples on the go.

How It Works

Turn the focus wheel slowly until every edge snaps into focus—done!

Runs on a single AA battery (not included) and comes backed by Carson’s limited lifetime warranty. Add the MicroBrite Plus to your cart today and open a whole new universe—no lab coat required!
