SWIR(短波长红外)成像是非破坏性检查的理想解决方案。它可以看到表面之下的东西,根据其 SWIR 光谱特征区分材料,并提供安全便捷的方式来确保产品质量。示例用途包括检查包装中的液体容量、检查密封容器的内容物,以及检测农产品中的损坏和污染物。此外,半导体行业中的用途包括硅晶圆图案检查和太阳能电池缺陷检测。
将 SWIR 成像集成到生产线中需要高行速率、高灵敏度相机,例如滨松的新型 C15333-10E InGaAs 线阵扫描相机。
C15333-10E InGaAs 线阵扫描相机已于 11 月 1 日发布,加入滨松久负盛名的 SWIR 和 NIR(近红外)成像技术产品阵容,其中包括用于高质量检查的 InGaAs 面阵相机。这款新相机是使用 SWIR 成像进行实时、在线非破坏性检查的理想选择,具有以下特点:
该相机的波长范围为 950 nm 至 1700 nm,在宽范围内具有高于 60% 的 QE。
该相机的 1024 像素线性阵列可捕获大视野,而我们的 InGaAs 面阵相机 C12741-03 具有 640 × 512 像素的分辨率。
可以实现最大 40 kHz/行的成像,因此,这款相机适用于高速在线检查。
滨松的电路设计可实现低读取噪声和高性能。像素校正功能可校正热像素、传感器变化和强度变化。
该相机采用千兆以太网接口,广泛应用于工业领域,支持 GigE Vision。
其紧凑轻便的设计使相机易于集成到检查系统中。
尺寸:49 mm(宽) × 49 mm(高) × 100 mm(深)(不包括凸起)。
重量:约 250 g
该线阵扫描相机的价格约为 InGaAs 面阵相机的 1/3。
由于与咖啡豆的大小和色调相似,在可见光图像中难以检测到的石头可以在 SWIR 图像中轻松检测到。
通过 SWIR 成像可以看到密封果汁或酸奶容器中的液位。
由于与米粒的大小和色调相似,在可见光图像中难以检测到的污染物可以在 SWIR 图像中轻松检测到。
可以检测到难以从视觉上区分的苹果上的损坏情况。
可以检查密封塑料容器的内容物,例如方便食品。
可以观察到硅晶圆的内部图案。
