Multispectral imaging camera is an important tool for two-dimensional (2-D) and  3-D spectroscopic analysis. First deployment was in space for remote sensing application, and it is now available for applying on sites or installing with drones. In this work, we propose an affordable palm-size wide-band 3-D multispectral imaging camera, covering broad blue, green, red, near infrared, and long wave infrared regions. Our palm-size 3-D multispectral imaging camera module is also embedded with our own designed software for capturing or recording  2-D spectral images with depth information from each spectral band simultaneously. These spectral images and depth information can be combined into 2-D and 3-D fused spectral images. Promising applications are in industry, agriculture, environment, public health, and security.
