    • A hand-held combined spectrophotometer and gloss meter quickly and effectively measures the appearance of a color sample. Light generated by a krypton-filled tungsten bulb shines on the sample and is reflected at 45.degree. into twenty-one photodiodes spaced at staggered intervals around the sample stage. A diffuser in the light path reflects a portion of the light back onto a pair of red and blue sensitive reference photodiodes. The output of the red and blue reference diodes compensates for changes in the output of the bulb. An LED produces light which shines on the color sample at an angle of 30.degree.. The reflected light is received by a large-area photodetector which determines the gloss of the sample. A viewing port permits the user to view the sample prior to measurement. When the viewing port door is opened, it automatically actuates the light and illuminates the sample for viewing. The viewing port door is automatically closed by a return spring. The instrument can be hand-held and operated by buttons on the front or a redundant button on the back. The operator may choose between a simple pass/fail appearance indication or can obtain more detailed information from an LCD display. The instrument may also be mounted for lab use and connected to exterior peripherals such as printers and the like.
    • 手持式组合分光光度计和光泽度计快速有效地测量了色样的外观。 由氪填充的钨球产生的光照射在样品上,并在45°反射到二十一个光电二极管,间隔在样品台周围。 光路中的扩散器将一部分光反射回一对红色和蓝色敏感的参考光电二极管。 红色和蓝色参考二极管的输出补偿灯泡输出的变化。 LED以30度的角度产生照射在颜色样品上的光。 反射光被大面积光电检测器接收,该大面积光电探测器确定样品的光泽度。 观察端口允许用户在测量之前观察样品。 当观察门打开时,它会自动启动灯光并照亮样品进行观察。 观察口门由复位弹簧自动关闭。 仪器可以通过前面的按钮或背面的冗余按钮进行手持和操作。 操作员可以在简单的通过/失败外观指示之间进行选择,或者可以从LCD显示器获得更详细的信息。 该仪器也可以安装用于实验室使用并且连接到诸如打印机等的外部外围设备。

    • A spectrophotometer includes: a sample-chamber lid capable of opening and closing an opening portion of a sample chamber for setting a sample and a reference sample; and sample-chamber lid opening-closing detecting means for detecting an opening-closing state of the sample-chamber lid, and the spectrophotometer is capable of controlling a measurement of a xenon flash tube as a light source, a spectroscope, a detector, an amplifier, an AD converter, a processor, a storage device, and a data display part. In the spectrophotometer, the light source is turned on after a state of the lid changing from an opening state to a closing state is detected in a sample-setting instruction state by the sample-chamber lid opening-closing detecting means; absorbancy, transmissivity, reflectivity, a sample-side energy value, or a reference-side energy value is measured; and a measurement result is displayed on the data display part.
    • 分光光度计包括:样品室盖,其能够打开和关闭用于设置样品和参考样品的样品室的开口部分; 以及用于检测样品室盖的打开 - 关闭状态的样品室盖打开 - 关闭检测装置,并且分光光度计能够控制作为光源的氙闪光管的测量,分光计,检测器, 放大器,AD转换器,处理器,存储设备和数据显示部件。 在分光光度计中,在样本室盖开闭检测单元的样本设定指示状态下,在从打开状态变为闭状态的状态之后,光源被接通, 测量吸收率,透射率,反射率,样品侧能量值或参考侧能量值; 并且在数据显示部分上显示测量结果。
