Micro-Ruler MR-1, traceable, for traceable measurements, resolution 0.01mm
The Micro-Ruler MR-1 is manufactured with anti-reflective chromium (30nm Cr2O3 over 70nm Cr) on soda-lime glass using highly accurate semiconductor manufacturing equipment.
The overall scale extends over 150mm with 0.01mm increments with all labeling in mm. The ruler is designed to be viewed from either side as the markings are both right reading and mirror images.
The overall size is 25mm x 180mm x 3mm thick, the linear expansion coefficient is 9 x 10-6ppm/ C. Over its full 150mm length, the ruler will predictably change dimensions by 1.35 m/ C.
The circles (diameter) and square boxes (side length) are 0.02, 0.05, 0.10, 0.50, 1.00, 2.00 and 5.00 mm.
They are ideal to measure magnification simultaneously in X and Y directions or to determine image distortions such as skew, pincushion, barreling or other non-linearities.
The measurement uncertainty (accuracy) is 0.5 m over 0-10mm and 2.5 m over the entire 150mm length as measured by the National Physical Laboratory (NPL) in the UK. NPL is the NIST counterpart in the UK.
The Geller MicroAnalytical Laboratory certification is made under ISO-17025 accreditation.
The MR-1 is offered as a certified reference material (a traceable standard), recertification is recommended in 5 year intervals.
Measurements should only by made by using pitch measurements, this is the distance between repeating parallel lines using either center-to-center or side-to-side spacing.

England Finder – S7 Slide (Transmitted Light)
The England Finder is a glass slide marked over the top surface in a way that a referenced position can be directly read relative to the locating edges.
All England Finders produced by Graticules for over 40 years are identical.
The purpose of the finder is to give the microscopist an easy method of recording the position of a particular field of interest, so that the same position can be re-located at a later date, or by another person in another laboratory, or when using any other England Finder on any other microscope.
The location of the arrows is identical for all England Finder slides. Mark a label on the left hand side of the specimen slide, indicating the orientation to be repeated.
By replacing the specimen slide with the England Finder, taking care not to disturb the position, the feature of interest can be noted.
The feature an also be re-located at another place or time by reversing the procedure.
Over 1,800 positions on a 76 x 26mm slide can be accurately located.
Slide thickness is 1.35mm 0.05mm.
Nominal line width is 0.025mm.

Sedgewick Rafter Counting Chambers are used in water analysis, culture inspection and applications where particles per unit volume must be ascertained. The Chamber consists of a 2mm thick clear base slide measuring 76 x 40mm. A rectangular chamber has been built onto this base. A coverglass is then placed atop the chamber. The Chamber measures 50mm L x 20mm W x 1mm deep with a grid-marked base of 1000 1mm squares. When the chamber is filled with liquid and the coverglass in place, a 1 ml volume of liquid is trapped. Under low magnification with a light microscope, each grid square is equivalent to 1 microliter(ul) of liquid. The S53 Sedgewick Rafter Counting Chamber is for many counting applications, APHA methods and where large particles and larger zooplankton in fluids are being analyzed. The S53 is plain glass without grid markings. The chamber holds 1 ml. of fluid. The S53 may be used with an eyepiece reticle where counting and sizing is required. Sedgewick Rafter Chambers are available in an economical plastic version for education and training, a professional version with high quality optical glass with a chromium surface image with counting grid, and a high quality optical glass without grid markings for large particles. The coverglass is compatible with all chamber versions. Note: Over the years the name of these slides has been incorrectly spelled as Sedgewick Rafter. The original methods were developed by William Thompson Sedgwick and George W. Rafter, so the true spelling should be Sedgwick Rafter. |
