REF-Si-4参考片Applicable于哪些系统？

适用于Filmetrics F20和F50薄膜厚度测量系统。4英寸大尺寸适配两种机型的样品台，不适用于其他F系列系统。

What is the difference between reference film and standard film?

参考片用于采集100%反射率基线，不含厚度信息。标准片具有已知精确厚度，用于校准测量精度。REF-Si-4是参考片，请勿用于厚度校准。

如何使用4英寸硅参考片？

将参考片放置在样品台上，使用系统采集参考光谱作为100%基线。测量样品时软件自动扣除参考光谱，获得准确反射率。

4英寸参考片有何优势？

大面积适合F20和F50的样品台，保证测量区域覆盖均匀，避免边缘效应。标准4英寸尺寸兼容常见样品夹具。

Product Highlights

Large size design -4 inches (approximately 100mm) diameter for easy access and positioning
High purity monocrystalline silicon - Provide a stable and flat reflectance curve with high reliability
Rapid baseline collection - Use reference film before measurement, the system automatically deducts the reference spectrum
Easy to operate - Directly placed on the sample stage without the need for additional fixation
原装正品 Filmetrics certification ensures the accuracy of reflectance baseline
F20/F50 compatible - Optimized sample table size specifically for these two models

Applicable scenarios

Establishment of reflectance baseline - Collect reference spectra before each measurement to obtain accurate reflectance
F20/F50 daily calibration - Provide stable reference for universal and flagship film thickness gauges
Large sample area coverage -4-inch size ensures uniform measurement spot and avoids edge effects
Equipment performance verification - Regularly check the stability and repeatability of the system's reflected signals
Quality system support - Provide traceable reflectance reference to meet calibration requirements

Frequently Asked Questions

What systems is REF-Si-4 suitable for? ▼

Suitable for Filmetrics F20 and F50 film thickness gauges, the 4-inch size perfectly fits their sample stage.

参考片与标准片有何区别？ ▼

The reference film is used to establish a 100% reflectance baseline, without thickness values. Standard plates have precise thickness and are used for thickness calibration. The two have different functions.

How to use a 4-inch reference film? ▼

Place it on the F20 or F50 sample stage to collect the reference spectrum, and the software automatically uses it as the baseline to obtain accurate reflectance during measurement.

Why use large-sized reference plates? ▼

The large size ensures complete coverage of the measurement spot area, avoids edge effects, and facilitates retrieval, placement, and positioning.

是原装正品吗？ ▼

Filmetrics certified original reference film, officially supplied by Nikon Technology, ensuring accurate and stable reflectance baseline.
