1、A-A-54386 22 April 1991 COMMERCIAL ITEM DESCRIPTION MICROSCOPE, OPTICAL (Binocular, Brightfield) The General Services Administration has authorized the use of this CommercialItem Description. This Comme.rcia1 Item Description covers a brightfield binocular microscope for histopathological and pathol

2、ogical studies for use inside medical laboratories and for outside field use. Salient Characteristics: Shall be an inclined binocular brightfield microscope for histopathological and pathological studies. Shall be a professional model that is suitable for diagnostic and research applications. A stud

3、ent grade microscope is not acceptable for use under this specification document. Shall be suitable for use in laboratories with adequate AC supply lines. Shall also be adaptable for outside field use where AC facilities are not available by the adaption of a mirror and fork assembly that shall be s

4、upplied as an accessory. Shall be supplied with the following accessories: A carrying case with a handle, a protective dust cover, and a mirror and fork assembly. Shall be suitable for operation from 50/60 Hz AC supply lines. The applicable AC line voltage shall be as indicated in the contract and/o

5、r purchase order (see “Ordering data paragraph). As a minimum, the microscope shall consist of a base with variable light source,stand with supporting arm and focusing controls, inclined binocular body (head), revolving nosepiece assembly with three planachromatic objectives and dust plug(s1, specim

6、en stage, mechanical stage, and substage condenser. The focusing of the microscope shall be controlled by the vertical movement of the specimen stage or the objective.

The light source shall be a 6 volt, 20 or 30 watt tungsten halogen la

8、mp. The circuitry for the light source shall include a continuous voltage (intensity) control, on-off switch and transformer. The lamp 8hall be supported in a lamp socket which has the facility for easy replacement of the bulb. The power cord shall be a flexible 3-conductor cord that terminates with

9、 a non-detachable 3-blade male plug. The illuminator shall have a filter holder with a removable blue filter and a built-in field diaphragm for Koehler illumination. The mirror and fork assembly shall be attachable to the base, for outside field use where AC facilities are not being used. The stand

10、shall house the focusing mechanism, and shall be attached to the base. The supporting arm of the stand shall support the binocular body. The focusing mechanism shall raise and lower the nosepiece assembly OP stage. The focusing mechanism shall include coarse and fine controls that are manually contr

11、olled by coarse and fine knob (dials) located in the lower position of both sides of the stand. For purposes of measuring specimen thickness, the fine adjustment shall be graduated in one (1) or two (2) micrometer divisions with one complete revolution representing 100 micrometers as a minimum. For

12、protecting an objective and specimen (slide), an adjustable mechanical stop shall be included in the stand to limit the travel of the coarse control. In addition, a safety clutch shall be included to stop the travel of the fine control mechanism in the event the operator continues to turn the fine c

13、ontrol when the objective makes contact with a slide or its top mounted cover slip. The binocular body (head) shall have eyepiece tubes with 1OX wide field eyepieces and eyeguard relief. The eyepiece tubes shall be inclined 30-40 degrees from the horizontal. The interpupillary distance (between eyep

14、iece tubes) shall be adjustable within a range that includes 56 to 72 millimeters (mm). The interpupillary adjustment shall include a millimeter scale for easy reference. Automatic tube length compensation shall be included if the tube length is affected by changes in the interpupillary settings. Th

15、e eyepiece tubes shall include provisions for installing micrometer discs. One eyepiece tube shall be focusable for acuity equalization of a users eye. The eypieces shall have a minimum 18 mm diameter field view and a minimum eye relief , distance 18.7 mm. The binocular body shall be 360 degrees rot

16、atable on the supporting arm (stand). The binocular body shall also be detachable for interchangeability with heads (e.g. a trinocular body for photomicrographic procedures). 2 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,- .f * A-A-543b bb m 99999

17、74 OObO9b5 b m A-A-54386 Three objectives shall be supplied with a quadruple or quintuple 360 degree revolving nosepiece having a ball detent index. Dust plugs shall be included in the unused objective hole(s) of the nosepiece. The objectives furnished shall be lox, 40X or 45X and 1OOX oil immersion

18、 planachromatics having numerical apertures of 0.25, 0.65 or 0.66 and 1.25 respectively. Each planachromatic objective shall have an image flatness over the entire field of view without any loss of sharpness or any loss of focus around the periplery of the field of view. The objectives shall be colo

19、r coded and marked for identification. In the nosepiece, the objectives shall be parfocal and parcentered so they are not affected by switching from one objective to another. The 40X, 45X and 100X objectives shall be retractable (i.e. spring loaded) when contact is made with a microscope slide or it

20、s cover slip. As an alternate to retractable objectives, the nosepiece assembly shall be retractable when an objective makes contact with a microscope slide or its cover slip. The specimen stage shall accommodate microscope slides that include 25 by 75 mm and 50 by 75 mm sizes. The specimen stage sh

21、all include a slide holder that is detachable by releasing a thumbscrew hold. The slide holder shall be in the form of a finger assembly that can grasp the sides of a microscope slide instead of its corners. The finger assembly shall also be retractable to allow more space on the specimen stage for

22、manual scanning of a microscope slide. The aperture width of the stage mount shall be not less than 25 mm. A right hand ungraduated mechanical stage, as a minimum, shall control the X-Y horizontal movement of the slide holder. The mechanical stage shall have ball bearing slideways in two perpendicul

23、ar directions that can give complete coverage under an objective of both size miscrscope slides. The substage condenser shall be located below the mechanical stage in a fork-type mount which is moved vertically by rack and pinion control for focusing purposes. The substage condenser shall have a num

24、erical aperture (N.A.) of 1.25 or 1.30, and shall include an integral iris diaphragm and shall provide an even full field illumination and a variable aperture control for all the objectives, i.e. from 1OX to 1OOX (oil immersion). The fork mount shall contain two knurled centering screws. The condens

25、er shall be supported by a snap action in the fork-type mount. The condenser shall also be removable from the fork-type mount without having to remove the centering screws. 3 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,- A-A-54386 66 m 9999974 006
