در بعضی موارد و کاربردها نیاز به بزرگ نمایی جسم و یا سطح مورد نظر می
باشد به همین منظور از
میکروسکوپ استفاده می گردد. با این میکروسکوپ شما می
توانید سطح پوست حشرات، گیاهان، سنگ ها، سکه و تمبر ها، جواهرات، بردهای
الکتریکی و ... را 1000برابر بزرگتر از اندازه واقعی مشاهده کنید.
میکروسکوپ وسیله ای است که در تمام مشاغل، حوزه ها مانند آموزش کودک و
نوجوان، تعمیرکاران الکترونیک، مهندسان، زیست شناسان، تعمیرکاران کامپیوتر و
موبایل و ... مورد استفاده قرار میگیرد.
میکروسکوپ USB بدون نیاز به باتری و
تنها با اتصال کابل USB به لپ تاپ، کامپیوتر و یا توسط OTG به گوشی های
هوشمند قابل راه اندازی می شود. منبع نوری قوی جهت دید کامل نمونه، با ۸
لامپ LED با نور قابل تنظیم تامین می گردد.
قابلیت فیلم برداری از نمونه
های متحرک، تهیه عکس و یا حتی نمایش زنده تصاویر و فیلم جهت کارهای
آزمایشگاهی و آموزشی، این لوپ اقتصادی ارزان قیمت را جایگزین یک
میکروسکوپ و دوربین میکروسکوپ کرده است.
Description:
A USB microscope is a
low-powered digital microscope that connects to a computer, normally via
a USB port. They are widely available at low cost for use at home or in
commerce. Their cost varies in the range of tens to thousands of
dollars.
In essence, USB microscopes are a webcam with a high-powered
macro lens and generally do not use transmitted light, but rely on
incident light from in-built LEDs lights situated next to the lens. The
light reflected from the sample then enters the camera lens. However,
the camera is usually sensitive enough not to need additional lighting.
As
the camera attaches directly to the USB port of a computer, eyepieces
are not required and the images are shown directly on the monitor.
They
usually offer modest magnifications (about 1× to 200×) at very low cost
without the need to use eyepieces, at least compared to conventional
stereomicroscopes for example. The quality of the final image depends on
the camera capacity or megapixels available with the system, varying
from 1.3 MP, 2 MP, 5 MP and upwards, as well as operator skill and
illumination quality. Both still images and videos can be recorded on
most systems.
The capacity of most USB microscopes is similar to that of most camera phones of about
2 megapixels.
Images
can be recorded and stored similar to a webcam on the computer. The
camera is usually fitted with a light source, although extra sources
(such as a fiber-optic light) can be used to highlight features of
interest in the object.
They generally offer a large depth of field
and a range of magnification when examining the image file on the
computer. The camera is so sensitive that it will generally work without
the need for any extra light source.
