LOMO Biolam Microscope

Damian’s views in his Lomo Biolam microscope

Damian used his renovated Lomo Biolam microscope to view the small organisms we found in our recent trip to Branston water park and cheek cells we collected from his mouth and stained with H&E staining on 2/2/2018.

Cheek cells x40 objective

X90 objective. All these images taken afocally from one side of the binoviewer on the Lomo, using hand-held Samsung S7 phone through x10 ocular and objective mentioned. There is also 1.5x multiplication effect from the binoviewer.

Therefore the magnification on image below with x90 objective = 10 x 90 x 1.5 = 1350 x. Contrast and brightness tweaked in the image editor on the Samsung S7 phone – no other processing:

The following photos are all with x10 objective, otherwise as above. They are of organisms from Branston water park:

The following picture shows Damian taking pictures through the ocular using the a ocal imaging technique of holding his camera up to the ocular.

Following renovation – excellent results!

10x objective – calibration slide – each division = 0.01mm:

Aspergillus – 20x objective (Aspergillus is a genus consisting of a few hundred mould species found in various climates worldwide. Aspergillus was first catalogued in 1729 by the Italian priest and biologist Pier Antonio Micheli. Viewing the fungi under a microscope, Micheli was reminded of the shape of an aspergillum, from Latin spargere, and named the genus accordingly [Wikipedia]):

Saprolegnia – 10x objective – see fruiting body and mycellum below (Saprolegnia is a genus of water moulds often called “cotton moulds” because of the characteristic white or grey fibrous patches they form [Wikipedia]):

Desmid x40 objective (a single-celled freshwater alga which appears to be composed of two rigid cells with a shared nucleus. The presence of desmids is usually an indicator of unpolluted water [Wikipedia]):

Renovating LOMO Biolam microscope 21/1/2018

Continuing from yesterday, Damian and I unbound the dovetail on the fine focus mechanism from its saddle plate – we have found that the fine focus on this microscope locks up as the grease dries and it takes a lot of work to sort it out. It is also possible to easily break some vital bits and – as we did – through away bits accidently – some like a curved springy washer might look broken – golden rule – be gentle and also don’t through anything away even if it looks broken when you are renovating instruments like this!

Renovating LOMO Biolam microscope – Damian and Andy

Damian bought around his Christmas present – his LOMO Biolam microscope – to my house this afternoon. He has done brilliantly renovating this machine and soon it will produce fantastic microscopic images. It is all metal and brass – gorgeous focusing mechanism inside like a clock!

Today, we had to dismantle the focus knob and mechanism to remove dried out grease which was preventing the mechanism from turning and also to do similar job on the rotating stage which wasn’t rotating! The latter had warped slightly over time and tended to bind. We produced some Heath Robinson hand made plastic washer of appropriate size and this prevented the binding – Damian is hoping to replace this in time with a purpose made washer.

Pictures from the renovation work today below.
