Sony W-300 Mounted On A Microscope
 Sony T-9 & T-10 Image Pages:   Images 1     Images 2 




The Sony W-300 can be mounted on the ocular tube of a stereozoom (dissecting) microscope using a Sony adapter ring and a 37mm (M) to T step ring. When attached to a Scopetronix Maxview Plus adapter, the camera slips into the eyepiece housing.


You simply focus through the camera's high resolution LCD screen. In order to avoid camera movement at slow shutter speeds, it is advisable to use the 2 second self timer. It is also advisable to use manual (M) settings on the camera.

37mm (M) to T step ring (37 mm to 42 mm); Scopetronix Maxview Plus adapter;
Note: the Maxview Plus shown above slips into an ocular tube 24 mm in diameter.
[24 mm extension can be replaced with a 30 mm extension for other microsopes.]

Advantages of Sony W-300 over a digital SLR:

  1. Smaller and lighter than SLR with extension rings.

  2. Brighter LCD display. Extension rings greatly reduce viewing light.

  3. Digital SLR requires 3 extension rings in order to eliminate vignetting.   

  4. The large 13.6 megapixel sensor has plenty of room for cropping.

Photographing Aphid Nymph With Microscope & Nikon D-90

Gland-tipped hairs on a rose bud. The dark aphid nymphs are 0.9 mm in length. Photographed with Sony W-300 through Bausch & Lomb dissecting microscope. Magnification 15x.

Rose bud photographed with Nikon D-90 and 60mm macro lens. The aphid nymph and gland-tipped hairs appear almost as large as in the above microscope image, but they are sharper.

Rose bud photographed with Sony W-300 through Bausch & Lomb dissecting microscope. The dew droplet is one millimeter (1/25th of an inch) in diameter. One gland-tipped hair is trapped within the tiny water droplet. The individual red gland at the tip of stalk is about 250 micrometers in diameter. Magnification 30x

Size of Grain of Table Salt (NaCl) Used in Wayne's Word Images

Microscopic view of three cuboidal grains of ordinary table salt (sodium chloride or NaCl). All three grains are just over one millimeter in length (red bar). Grains of table salt vary slightly in size, but three average grains stacked together adds up to approximately one mm. If three grains equal one millimeter in length, then a single grain is approximately 0.3 mm or 0.03 cm on a side.

A Minute Red Spider Mite

A red spider mite collected on a navel orange 4 January 2010. It is compared in size with the head of an ordinary straight pin (1.5 mm in diameter) and a cuboidal grain of ordinary table salt (NaCl). The width of the mite's body is about 0.6 mm, roughly equivalent to two average grains of table salt placed side-by-side. Spider mites resemble miniature spiders and actually belong the same arthropod class as spiders (Arachnida). They are placed in the subclass Acari along with other mites and ticks. There are 1600 species of mites in the family Tetranychidae, so assigning a genus or species to this image would be purely conjecture on my part. Some of the best known red spider mites belong to the genus Tetranychus. The common red spider mite on citrus trees is Panonychus citri. Like hymenopterans (bees and wasps) and some homopterans (aphids), sex determination depends on whether the egg is fertilized or not. Dipolid (2n) females develop from fertilized eggs and haploid (n) males develop from unfertilized eggs. Unmated females lay parthenogenetic eggs and their offspring are exclusively male, a term called arrhenotokous. Red spider mites are polyphagous and feed on many different species of plants, including vegetables and ornamentals. They suck the contents of leaf cells, leaving minute spots or scars where the epidermal cells have been destroyed. Although individual lesions are very small, commensurate with the small size of mites, infestations of thousands of spider mites can significantly damage the leaves and reduce their photosynthetic ability.

A Technique To Show The Air Spaces & Vein (Nerve) On The Duckweed Lemna valdiviana

Ventral view of Lemna valdiviana showing a single vein that extends 3/4 of the distance between the node (point of root attachment) and apex of the plant body. According to Landolt, this is one of the most reliable characteristics to separate it from L. minuta because of the variability of these two species under different growing conditions. The original image color was inverted using Photoshop CS-1.
