Pimoroni Microscope Lens for Raspberry Pi HQ Camera Review: Tiny Details

(Image credit score: Tom’s Hardware)

With the discharge of the Raspberry Pi HQ digital camera  got here a brand new international of interchangeable lenses for Raspberry Pi images. For essentially the most section those lenses had been for basic images tasks, however a brand new $28 lens ($49.80 with devoted stand) on sale by the use of Pimoroni gives the danger to view the microscopic international round us.

Measuring 4.21 inches (107 mm ) top and1.53 inches (39 mm) extensive, the all-black Pimoroni Microscope Lens screws at once into the Raspberry Pi HQ digital camera, becoming snugly over the sensor the use of a CS/C adapter. It can’t be used with another form of Raspberry Pi digital camera module.

A knurled adjustment ring supplies a way to change the magnification issue from 0.12 to 1.8x, roughly 60 to 900x magnification. The Pimoroni Microscope Lens’s center of attention is about by way of shifting the lens closer to or further from the objective, which calls for a gradual hand or a microscope stand, which may also be purchased as a package with the lens. In our exams we used the bundled microscope stand to make certain that our pictures had been sharp.

After enabling the digital camera in raspi-config, we took our first image, and all we noticed used to be a black symbol. To use this lens you will have to first set the zoom stage the use of the knurled ring, then set the point of interest by way of shifting the lens closer / further from the objective. If you might be the use of the microscope stand, as we did, there’s a huge knurled black dial which can be utilized for high-quality tuning the point of interest. This will take a little time to get proper and the use of the terminal command raspistill -k  will supply a are living preview that lets you set the zoom and center of attention.

Picture high quality is excellent, in large part because of the 12.3 megapixel Sony IMX477R sensor at the Raspberry Pi HQ Camera, however the lens supplies a transparent and distortion loose symbol. Our check pictures had been all captured on the most solution to be had: 4056 x 3040 and the extent of element is astounding bearing in mind the price of this lens.

In our exams we set the lens to most magnification and positioned an WS2812 “NeoPixel” LED measuring 5 mm x 5mm within the middle of the picture. At this stage of magnification we had been ready to view the circuit pathways of the WS2812 chip on the middle of the LED, a chip that measures 1 mm x 1.3mm.

We additionally recorded a 1080p video of shifting round a 2-pence coin and the consequences had been similarly spectacular.

Uses Cases and Total Cost

The Pimoroni Microscope Lens can be excellent for house or faculty science classes, enabling the experiment to be recorded to the Raspberry Pi with only some strains of code. The lens additionally lends itself to electronics tasks, particularly SMD soldering with small floor mount elements.

To use the Pimoroni Microscope Lens, you’ll want any Raspberry Pi style. Even a Raspberry Pi Zero W ($10) can be excellent for this mission. The HQ Camera is $50, and the lens and stand pack is $49.80. All of this involves $109.80 for a equipment which is able to seize more than 4K pictures, and 1080P video.

If you don’t care about Raspberry Pi, HDMI microscopes are to be had from below $100 for a fundamental unit which is able to seize 1080P pictures and video. However, Raspberry Pi lovers will possibly have some or lots of the elements to construct this one readily available so their price will probably be much less.

Bottom Line

This Pimoroni Microscope Lens is a handy gizmo for exploring the whole lot from circuit forums to on a regular basis items. However, you’ll surely need the non-compulsory stand. The proven fact that it connects to a Raspberry Pi signifies that this lens is a part of a perfect setup in the school room or house workshop and one that you’ll program and even keep watch over remotely.
