Newly Developed Equipped with Natural Light LEDs
General Color Rendering CRI98
The average color rending index achieves an unprecedented level of CRI98.
Colors can be faithfully observed as they originally appear in the sample.
Note:This is the average rendering of evaluated test colors (eight colors specified by JIS) (correlated color temperature: 5000 K). This value is for reference only.

What are color rendering properties ?
For example, white paper appears slightly orange in color under an incandescent
lamp. The type of light source used affects the visibility of an object's color. How a
certain light source brings out color in an object is termed "color rendering" and the
characteristics used for the purpose are a light source's "color rendering properties."
In general, light sources with good “color rendering properties” are able to light up an
object without introducing any differeces from its original hue.

In addition, excellent performance is also provided in inspection
for specks or color spots on PCB surfaces and observation in
scientific fields, such as for cells in biology.

Note:Compared to common lights.
The amount of stress on the eyes by many-hour or closeup observation will be reduced.
Eye Stress from Light
Structure of the Eye
Eyestrain
The shorter-wavelenght is the greater amount of energy the light has.
The shortor-wavelength light among visible light reaches the retine and may
stress on it.

Psychological and Physiological Effects
People feel most natural ( i.e., psychologically and physiologically relaxed ) in
sunlight, and so bluish white light, which has a high correlated color temperature,
produces a sense of discomfort and results in psychological and physiological
stress.

Retina
The light of the CNR contains few components at short wavelengths, and so the retina
is not exposed to significant stress. The correlated color temperature of 5000 K is
close to sunlight, and so observation can be performed without discomfort.

A Natural Light LED can faithfully reproduce colors because
the light components are close to sunlight.

It is possible to view with unprecedentedly high color rendering, particularly for violet ( R8 ) , red ( R9 ) , blue ( R12 ) , and yellow ( R10 ) .
Spectral Distribution
The Natural Light LED has a similar spectral distribution as sunlight compared to other light sources, with broad range of
wavelengths rather than a disproportionate weight at specific wavelengths. -ideal to reproduce an object’s original color.
Spectral distribution of “Natural Light LED”
Color reproduction is extensive with no
disproportionate weight at specific
wavelengths.
Spectral distribution of sunlight
Spectral distribution of common white LED
Visible light
UV
IR
The wavelengths are very strong in the
blue range, and the light appears
somewhat bluish, so color reproduction
is insufficient.
Spectral distribution of fluorescent light
Specific wavelengths are excessively
strong, and the reproduction for other
colors is insufficient.
Correlated Color Temperature
CCT is 5,000 K. This means Natural Light LED allows to see objects in their natural color.
Light Intensity of 35,000 lx, the Highest
in the Industry
Collective Lens Image
Our unique collective lens enables bright illumination
in the observation field of view.

Notes:
1) This applies for a WD of 110 mm. (The value is for reference only.)
2) Achieves the highest level of brightness for LED lights for microscopes.

CCS's Unique Mounting Method
(Bottom-up Method)
Securing a Work Area without Any Changes
Mounting Methods of Other Companies
(Suspended Method)
A unique mounting method eliminates the need to
make the work area narrower under the objective
lens. Work can be performed without thinking
about the light when the test samples or workpiece
is moved while observing.
Low Power Consumption, Energy Savings,
and Long Lifetime
No Infrared or ultraviolet radiation
Only minimal amaunts of infrared and ultraviolet
radation are emitted, which greatly minimizes color
fading and other damage caused to target objects.
Low power consumption of 5.7 W.
The lifetime is longer than that of fluorescent lights.
Greatly helps reduce running costs.
