A crossed-scale reticle provides two graduated axes with a shared origin. It supports X/Y length and offset comparisons in the same microscope field after calibration for the optical setup.
Specify optical glass or fused silica, overall dimensions, thickness, pattern-side orientation and the clear aperture. Define transmission, reflectance or optical density at the working wavelength when optical contrast is critical.
Crossed scales provide an origin and perpendicular references for comparing X/Y extent or offsets. Both axes require specimen-plane calibration when used through a microscope.
Calibrate eyepiece divisions against a stage scaleOrthogonality and intersection placement belong to the component geometry. Camera pixel scaling, image rotation and stage alignment affect the installed coordinate system and require their own checks.
Optical references in measuring instrumentsA crossed-scale reticle provides two graduated axes with a shared origin. It supports X/Y length and offset comparisons in the same microscope field after calibration for the optical setup.
Choose a single scale for measurements along one direction. Choose crossed scales for two perpendicular directions or for measurements that must share a common origin. Rotate the reference or specimen so the measured feature follows the scale axis.
An eyepiece division has no fixed specimen value until calibrated. A stage micrometer supplies a known length at the specimen plane; a crosshair without graduations supplies an alignment reference, not a length scale.
Scale length, graduation interval, numbering, line width and a single or crossed layout define the visible reference. Disc diameter, thickness, seating face and pattern position define its fit in the eyepiece.
A patterned reticle disc for the eyepiece or measuring magnifier. Its physical scale geometry is separate from the specimen calibration established on the assembled microscope.
Orthogonal graduations for comparing X and Y dimensions in the same field.
No. It is a physical distance in the reticle plane. Its specimen equivalent depends on the optical magnification and is established with a stage reference.
Keep a separate conversion for each objective and intermediate optical configuration. Nominal objective labels alone do not capture every magnification change.
Measure the reticle seat, thickness clearance and usable pattern field. The outside diameter of the eyepiece housing is not the reticle diameter.
Crossed-scale reticles place graduated X and Y axes at one origin for comparing length and offset in a single field.
Specify the two division scales and their shared origin. Match orientation and reading direction to the instrument.
X/Y division spacing, scale lengths, numbering, origin, mounting dimensions and optical plane.
The reticle usually sits inside the viewing optics. An XY stage micrometer sits at the specimen plane; they have different calibration and installation roles.
