A process for forming, by using a microscope, an image of combusted, incinerated, or cremated human or animal ashes material, the image comprising different colors, the method comprising the steps of: i. providing a bright field microscope having a function of fluorescence microscopy, the bright field microscope comprising two dichroic filters, a 490 nm to 520 nm two-band filter, a 490 nm interference blue filter, an excitation filter or emission filter for filtering an excitation wavelength of 372 nm and an emission wavelength of 456 nm, and a camera connected to the bright field microscope; ii. providing a dried human or animal ashes by drying a predetermined amount of the combusted, incinerated, or cremated human or animal ashes material; iii. placing the dried human or animal ashes sample on a slide, covering the dried human or animal ashes sample with a coverslip, and placing the covered dried human or animal ashes sample on the bright field microscope; iv. reflecting the light to be filtered by the two dichroic filters of the bright field microscope to separate the light into two chromatic beams; v. selecting an excitation wavelength and an emission wavelength using the excitation filter or emission filter to determine spectral properties of the dried human or animal ashes sample; vi. combining the two-band filter with the interference blue filter and the excitation filter or emission filter for filtering an excitation wavelength of 372 nm and an emission wavelength of 456 nm within the ultraviolet spectrum; vii. observing, with a camera through the bright field microscope, the image of the dried human or animal ashes sample, wherein the image comprising different colors. i. providing a bright field microscope having a function of fluorescence microscopy, the bright field microscope comprising two dichroic filters, a 490 nm to 520 nm two-band filter, a 490 nm interference blue filter, an excitation filter or emission filter for filtering an excitation wavelength of 372 nm and an emission wavelength of 456 nm, and a camera connected to the bright field microscope; ii. providing a dried human or animal ashes by drying a predetermined amount of the combusted, incinerated, or cremated human or animal ashes material; iii. placing the dried human or animal ashes sample on a slide, covering the dried human or animal ashes sample with a coverslip, and placing the covered dried human or animal ashes sample on the bright field microscope; iv. reflecting the light to be filtered by the two dichroic filters of the bright field microscope to separate the light into two chromatic beams; v. selecting an excitation wavelength and an emission wavelength using the excitation filter or emission filter to determine spectral properties of the dried human or animal ashes sample; vi. combining the two-band filter with the interference blue filter and the excitation filter or emission filter for filtering an excitation wavelength of 372 nm and an emission wavelength of 456 nm within the ultraviolet spectrum; vii. observing, with a camera through the bright field microscope, the image of the dried human or animal ashes sample, wherein the image comprising different colors.
