Dear confocalist,

I am looking for a suitable source of tiny bandpass filters. Small diameter and small thickness. Diameter down to 1 mm or maybe even less, and thickness below 1 mm. Probably these items have to be custom made. But there are many manufacturers for optical filters on the market, and therefore I wanted to hear if you can give any recommendations to me about suitable companies for this.

Thank you,
Martin

Hi Martin,

Depending on the wavelength you need, old DVD or blueray drives might be a solution.

Dear Dr. Köhler--

Would any of the colored glasses from Schott work for you?  The
disadvantage is that optical density will be a function of thickness but
the advantage would be the ability to fabricate the glass into any shape
that you might want.

Good luck!

Hi Martin,

Please email Chroma and Semrock. I believe the tele-communications
industry used small diameter filters.

Web links to these two, and lots of other filter companies, in the first
section of

Pilot Projects for a Human Cell Atlas ... request for applications posted by Chan Zuckerberg Initiative

Dear confocal listserv, Want money? Work on cells?

Pilot Projects for a Human Cell Atlas ... request for applications
posted by Chan Zuckerberg Initiative

https://chanzuckerberg.com/initiatives/rfa

REQUEST FOR APPLICATIONS

Pilot Projects for a Human Cell Atlas

OPPORTUNITY

The goal of the International Human Cell Atlas project is to create a
reference atlas of all cells in the healthy human body as a resource for
studies of health and disease. As part of this effort, the Chan
Zuckerberg Initiative seeks applications to support the Human Cell Atlas
community’s convergence around standards, protocols, and best practices
for the creation of a freely and openly available reference database of
healthy human cells and tissues.

Project Specifications

We expect the reference Cell Atlas to ultimately include a variety of
data types, including single-cell RNA sequencing, in situ hybridization
imaging, proteomics, metabolomics, epigenetic information, low- and
high-resolution images of biological samples, and more. For the initial
phases of the project, we are especially interested in groups that can
help evaluate protocols and best practices for the collection of
single-cell molecular data, ideally by directly comparing multiple
approaches to tissue preparation, data generation, or data analysis.

Example pilot project goals might include, but are not limited to:

Systematic comparisons of tissue preparation and preservation, sample
handling, and cell dissociation approaches for a variety of human
tissues and organs.
Systematic comparisons of sequencing technologies, protocols, and
resulting datasets.
Evaluation of experimental replicability, including comparing different
experimental procedures within the same lab, and similar procedures
across labs.
Comparison of image-based approaches, such as single-molecule
fluorescent in situ hybridization imaging (smFISH), with
sequencing-based approaches.
Comparison of different multiplexing strategies for image-based approaches.
Evaluating suitability of experimental strategies to different
computational pipelines.
Evaluation of biological replicability depending on donor age, sex, or
tissue type.
Evaluation of multiple tissues from one individual, compared to
different individuals.
Generation of new benchmark or validation datasets.
We are primarily interested in assembling a broad and biologically
compelling set of human tissues for the reference atlas, but in this
pilot phase, we will also consider proposals for obtaining data from
cell lines, organoids, or non-human animals.

*COMMERCIAL RESPONSE*

Hello Martin,

We can do this with certain constraints regarding filter shape and the size
of the required clear aperture.

Please feel free to contact me.

Best,
Jeff

Hi,

we had filters cut to custom size by AHF (www.ahf.de). They've been very
helpful and we were happy with the result.

Best,

Christian

Z-drift compensation Olympus & Imspector

Dear all,

we want to upgrade our Abberior STED on an Olympus stand with the
Olympus IX3-ZDC-12 z-drift compensation unit. The system is managed with
the Imspector software.
There is some sort of prize gap between Olympus and Abberior, in a
rather unreasonable manner.
We would like to get the unit built into our microscope stand directly
from Olympus. Does anyone have experience on the neccessary improvments,
which then will have to be done within the Imspector software, as
Olympus does not deliver that.

Many thanks for everey valuable input .

Cheers, Ralf

Hello,

The power supply box for the Argon laser on our old Olympus Fluoview 300
system exploded.
In order to check the laser condition I need this box but I was told by
Olympus it is not available from the vendor : Melles Griot.

Could anybody lend me a unit to test the laser? Or sell/donate one ( I
will cover the shipping charges of course).

cheers and have a lovely day

Magdalena
